In this presentation we will share the latest results on test and design of products that combine a hybrid of two waveguide technologies in one PLC. The Silica waveguide provides good coupling to fiber. In Silica we have developed cascade AWG chips with a filter function that has box-shape with low loss of less than 2dB and good isolation. In Nitride we can achieve small bend radius to minimize the chip size. Nitride also allows for smaller modes that are better suited to couple directly to laser diode and Silicon photonics with low coupling loss.
Henk Bulthuis is director of the R&D group of Broadex Technologies UK, formerly Kaiam Europe, Gemfire Europe, Avanex, Alcatel Optronics and Kymata. He co-founded BBV software BV and BBV design BV which were acquired by Kymata in 2000. Close to 800 mask reticles and 2000 of his PLC/PIC designs were simulated, layed out fabricated and tested. Most of the designs were made in glass or silicon technologies.
