Panel: Has silicon photonics got the required scalability to displace InP?
Silicon photonics has attracted the interest of many in large corporations, SMEs, and academics as a potential replacement to the incumbent PIC technology InP. SiP offers natural electronics and photonics integration but can’t source laser light unless custom techniques of packaging, bonding etc are utilized with InP based sources. Also, given that SiP may well be on 200mm and 300mm wafers, it is also not clear if the volume requirements are at a level to attract serious attention in large scale fabs. Given these conditions, the question remains to ask if SiP can be truly scalable towards $1/Gbps at 400Gbps data rates and above (for any distance)?
Panel: High volume and high performance opportunities for PICs
Will transceivers ever achieve super high volumes to allow scalability in cost and performance, and if so, what would be the common large volume platforms, and more specifically, what would be the transceiver format/form factor. Will these volumes be in the 50m or 100m or 200m level? What percentage of transceivers in a decade will contain PICs, and if so where would you expect to see a PIC being used in a transceiver. Will PICs in transceivers will be three chip, two chip, or one chip (OEIC) solutions? Lastly, will transceivers ever go away or evolve to new designs, especially with COBO and other non-pluggable innovations?
Moving the data: PICs for cloud computing and telecoms
Big data analysis - a golden opportunity for silicon photonics
Yuichi Nakamura - NEC
Today, information and communication technology (ICT) systems make a valuable contribution to solving social problems, with techniques such as big data analysis able to enrich our daily life in many ways. Evolution in processing architecture puts faster performance in reach, but only if innovation in interface architecture among servers can be achieved to avoid the bottleneck of data communication. One solution is optical communication among the servers, and to share our thoughts on the topic we will examine the latest trends in silicon photonics as a way forwards, as well as looking ahead at the advantages of optical connection further into the future.
Silicon Photonics for Distributed data centre interconnects
Radha Nagarajan - Inphi
Modern day data centre interconnects are not limited by distances. Although the data centres themselves are physical locations, limited in land area, the optical interconnects between them could span anywhere from 10’s km of terrestrial distances to 1000’s of km subsea routes. In this talk, we will focus on the application of Silicon photonics to regional, latency limited data centre interconnects. The discussion will be on low power, high speed, switch pluggable modules that allow for the physical disaggregation of the data centre locations, thus enabling highly redundant and distributed data centre architectures.
Silicon Photonics, current status and future perspectives
Eric Mounier - Yole Développement
With Big Data getting bigger by the second, transporting this level of data with existing technologies will soon reach its limit in terms of power consumption, density, and weight. It is now sure that photons will continue replacing electrons throughout networks, including in the Data Centre, the rack, and very soon on the board. The question is: how to achieve this at low cost? The answer is quite simple: market volume in million units will allow scale factor that will drive the cost down. This is the quite simple equation that Silicon Photonics, fundamentally a semiconductor-based process, must solve. Si photonics has been under development for years, but there are still only a few products on the market. However, now that this technology is being pushed hard by large webcom companies like Google, Amazon, Facebook, or Microsoft, we believe we have reached the tipping point that precedes massive growth. In my talk, I will present market forecast for Si Photonics for Data Centres applications and will review the industrial landscape and technical challenges.
PIC opportunities for datacentres
Vincent Zeng - Facebook
The growth in network bandwidth at Mega Data-Centers is putting pressure on the photonic technologies to rapidly deliver high-bandwidth interconnects at high volume. In this talk, we will describe Facebook’s scale and some of the trends that are fueling this bandwidth growth. This bandwidth growth will fuel innovation not only in technology, but also in manufacturing processes as traditional technologies struggle to meet the volume challenge. This will change the optics development and commercialization process and open the door for Photonic Integrated Circuits as yield management drives improvements in the wafer-level and advanced photonics packaging with scaled manufacturability and automation.
The Zettabyte is not enough: Volume handling for InP, silicon photonics, and hybrid photonic integration
Martin Schell - Fraunhofer HHI
Cisco with its Visual Networking Index has announced the Zettabyte era, as in 2016 the annual run rate for global IP traffic was 1.2 ZB per year. On the other hand, a single InP 3” wafer with lasers or detectors supports some 30,000 devices @ 50Gbit/sec each, equating to roughly 5 ZB per year, when operated continuously. Hence, the success of a particular integration platform relies on its capability of either being able to deal with rather low wafer numbers, or adding (senseful) functionality to increase the per-device-area, or to radically increase the market by going outside telecom/datacom. The presentation will compare InP monolithic, Silicon Photonics, and polymer based hybrid photonic integration with respect to this regard.
III-V photonic integrated circuits for telecoms and beyond
Weiming Yao - PITC, TU/e
The generic foundry approach to photonic integrated circuits (PIC) has enabled easy access to PIC technology by lowering its entry and prototyping costs, leading to the wider adoption of optical chips across many application areas. We focus here on the recent progress and the challenges of high-capacity WDM transmitters on III-V material for data and telecom that have been fabricated in such generic integration platforms. Furthermore, we outline the platform architecture of the next generation PICs that support extended scaling in device footprint and performance and at the same time assure a more intimate integration with electronics.
Massive array integration and the need for a holistic digital/analog optics/electronics co-design
Peter Winzer - Nokia Bell Labs
The need for 10-Tb/s interfaces operating in 1-Pb/s systems and networks asks for massive array integration across both wavelength and spatial domains. While being accompanied by a series of new device and packaging challenges, the close integration of massive opto-electronic arrays also bears a wealth of opportunities arising from a holistic view of a fully integrated digital-electronics/analog-optics communications engine. Options include the mitigation of integration-induced array impairments using powerful digital signal processing, and the ample use of comb sources as external optical power supplies. This talk will discuss challenges and solution paths towards a 10-Tb/s optics-in/optics-out digital communications engines.
Quo Vadis – Industrial High Precision 3D Printing
Ruth Houbertz - Multiphoton Optics
Driven by IoT, Industry 4.0, and social media - the amount of data to be transferred is increasing tremendously, pushing the need for energy-efficient device concepts for a vast variety of products. Low energy data transfer can be achieved by optical interconnects, or by introducing optical elements such as specially designed microlenses into semiconductor laser packaging using High Precision 3D Printing. This allows device makers to significantly reduce process steps independently of the packaging task. Scalability and high throughput with fabrication times from seconds (for optical waveguides and single microlenses) to only a few minutes (for more complex lens systems) are explored as part of the presentation.

The explosive growth of integrated photonics both in datacenters, telecom as well as non-communications applications, especially from a market standpoint are opening new doors for scalable PIC platforms. Polymer based PICs offer scalability with increased data-rates as well as lower cost structures and provide an excellent vehicle to address the 'purple brick walls’ (cost/performance) that have appeared in photonics roadmaps.
Programmable photonic ICs: making optical devices more versatile
Wim Bogaerts - Ghent University/imec
Most of today’s photonic ICs are designed for a specific purpose and targeted at a specific application, in that they resemble an electronic application-specific integrated circuit (ASIC). But with PIC technologies and design processes now starting to support larger-scale integration, this opens the door to more generic photonics ICs that can be reconfigured or programmed for diverse applications, resembling electronic FPGAs. Such circuits can implement programmable wavelength filters for WDM or microwave photonics, tunable delay lines, multi-format transceivers or optical information processors. In our talk, we will discuss the current state of this new field in PICs, and the future challenges and applications.
Coupling electronics and photonics – promising paths for device-makers to explore
Silicon photonics packaging is a crucial technology for the commercialisation of photonic integrated circuits (PICs) - especially with the drive towards small form-factor and lower cost modules. Comprehensive capabilities have been established in device libraries and associated tool boxes to enable the integration of electronic chips, low cost lateral optical fibre assembly and automated laser diode assembly. Further innovation in the areas of optical packaging, electronic-photonic integrated circuit (EPIC) full co-design will lead to a more integrated solution for enabling optimal performance and cost effectiveness. These developments will help to achieve the next milestones in Si-Photonics and contribute to addressing overall system requirements - boosting the deployment of products in the market.
Design Flows for Monolithically Integrated Electronic-Photonic Systems-on-Chip
Mark Wade - Ayar Labs
As electrical I/O is approaching fundamental bandwidth scaling limits, it is necessary to integrate optical devices and systems more deeply with electronics. Once optical devices are monolithically integrated on the same die as CMOS transistors, the optical devices must follow the same design methodology as high-volume microelectronics. This talk will present a design flow that was used to demonstrate monolithic SoC’s such as a dual-core CPU with photonic I/O, a low-latency network protocol, and a 400G transmitter with >1Tbps/mm2 bandwidth density and 0.83 pJ/bit energy efficiency.
Novel Heterogeneous Integrated Photonic Platforms on Silicon
Sasan Fathpour - CREOL, The College of Optics & Photonics
Silicon photonics owes its success to the versatile and high-quality silicon-on-insulator (SOI) wafers. However, the SOI technology has several limitations for some important applications such as integrated nonlinear optics and mid-infrared photonics. We have been developing several novel heterogeneous integrated photonic platforms and have demonstrated various high-performance devices and circuits on them. Example heterogeneous platforms developed for the first time by our team at CREOL are lithium niobate on silicon, silicon on lithium niobate, silicon on nitride, and all-silicon membranes. These novel approaches and associated fabrication methods will be presented together with a discussion on the performance of fabricated devices and circuits.
Integrating photonic building blocks towards complete electro-optical computing
Yvain Thonnart - CEA-Leti
Efficient data transfer between IOs, memories and cores is a key element of high-performance computing. The trend for massively parallel architectures increases the communication needs, at the cost of increasing latency and power consumption. To overcome this, we are investigating the potential of optical communication on large silicon interposers, to stack and connect computing and memory chiplets together. In this talk, we present recent developments at CEA-Leti considering the architectural, design and fabrication aspects of optical interposers, from digital and high-speed analog elements, to the optical devices, in view of the power and thermal constraints. In addition, we share our insight on the integration of these building blocks in a complete electro-optical computing module.
III-V membrane lasers on silicon for datacom and computercom applications
Shinji Matsuo - NTT
Lasers on silicon substrate are expected to fabricate large-scale PICs with low cost because they can be heterogeneously integrated with low-cost Si photonics devices. In addition to the cost issue, reducing the power consumption of laser is quite important because it limits the integration density of PIC. For this purpose, we have developed membrane lasers on SiO2/Si substrate, in which large optical confinement factor enables us to enhance the modulation efficiency of directly modulated laser. We employ epitaxial regrowth to fabricate buried heterostructure on directly bonded III-V layers on SiO2/Si substrate, which allows us to employ large-scale Si substrate for fabricating lasers.
Delivering the goods: advances in PIC manufacturing
Silicon nitride based TriPleX PIC modules in a broad range of applications
Arne Leinse - LioniX
The silicon nitride based waveguide technology (TriPleX™) of LioniX International enables new applications due to its unique properties. The ultra-low loss over a broad wavelength range (from 405-2350 nm), the ability to create spot size converters, the integration of low power phase shifters and the hybrid integration with other platforms. Supplying PIC based modules instead of PICs only moved the mature PIC platform from technology push to market pull. Fully assembled plug and play modules lower the access barrier for the development of new applications and the hybrid combination with for instance InP enables unique functionalities. In this presentation application examples of PIC based modules will be described in more detail and an outlook will be given to future technology developments.

Inline wafer-scale photonic testing to boost PIC manufacturing efficiency
Jessie Rosenberg - IBM
One of the cornerstones of high throughput CMOS processing is inline monitoring and waferscale test functionality. In addition to validating device performance and generating statistical data, testing at early stages in fabrication provides a critical feedback signal for the health of the manufacturing line and enables problems to be diagnosed well before the expensive back-end-of-line and packaging processes have been completed. Combined electrical and optical inline and waferscale testing can provide yield metrics, lookup tables, and built-in self-test in an automated fashion, reducing cost by ensuring that further fabrication and packaging only proceeds on known-good-devices.
99% Alignment Cost Reduction through Novel Parallel Technology— An Enabler for SiP Production Economics
Scott Jordan - Physik Instrumente
We are confronted with many challenges for economical, repetitive manufacturing of Silicon Photonics devices. One universal challenge that has only recently been addressed is for fast, nanoscale alignment of optical fibers, micro-optical elements and active and passive photonic devices in multi-channel, arrayed formats. Since these needs begin with probing at the wafer level and recur through final packaging, the benefits of higher-throughput alignment are profound for cost and yield. Legacy alignment technologies are problematic for the multiple, interacting inputs and outputs commonly encountered in today’s SiP devices. With these older technologies, time-consuming, costly, repetitive alignment loops were required to achieve global alignment, leading to unacceptable production economics as quantities scale. These challenges have led to the broad adoption of a novel, parallel alignment technology with native multi-channel and multi-element simultaneous-optimization capabilities which we discuss in depth. It can perform global optimization across the inputs and outputs of complex photonic and optoelectronic devices, in multiple degrees of freedom, in one rapid step. Its high throughput addresses multiple emerging process pain-points from wafer test to packaging and chip test. This new alignment technology has by now been integrated into wafer probers and volume packaging and chip-test systems. It is facilitating testing and packaging operations with high throughput and yield. Throughput improvements have exceeded two orders of magnitude versus traditional approaches.

Photonic Integration is key to deal with the challenges in optical solutions for data- and telecom, in terms of cost, performance and scalability. InP has proven itself as the material of choice for lasers and we show that Photonic Integration on InP is a solution to tackle all these. The benefits for InP are clear: full monolithic integration of lasers, amplifiers as well as modulators and passives enables a versatile, flexible and reliable platform to build PICs for the current needs. The improved manufacturing capabilities a.o. using high resolution ArF lithography clearly indicate the path to high volume manufacturing at low cost with improved performance.

PIC Design: From Concept to Manufacture
Robert Scarmozzino - Synopsys
The emerging photonic foundry industry needs flexible design tools in order to expand support for commercial applications. Designers need tools that work both out of and outside the box to creatively and inexpensively explore new applications before committing to costly prototyping. The Synopsys design flow meets this need through tightly integrated concept development at both the circuit and component levels. Design starts at the schematic level using foundry-specific or custom PDK components to create PICs, proceeds to system-level simulation, and ultimately concludes with automated layout for manufacture. Custom PDK components are automatically generated using the industry’s widest range of available simulation methods for passive and active photonic devices.

Biochemical analytics and diagnostics are pushing forward into areas outside the laboratory and towards mobile and stand-alone field applications. Efficient diagnostic devices are easy to use, lightweight and provide reliable results. The focus of applied research is to validate the efficient selection of technologies and enable their smooth integration into small packages. Photonic integrated circuits have a key role to play in driving performance and contributing to a compact final device, and -- to highlight these elements -- this talk presents the transformation of a PIC into a biosensor. To allow automated biochemical process execution, the PIC is combined with a fluidic circuit. The system application targets explanatory exploration missions in terms of a wet chemical payload - for example, on board a Mars-rover. Nevertheless, the development procedure can also be transferred to other decentralized diagnostic applications on earth.
