Semi-insulating substrate based generic InP photonic integration platform

In the European projects EuroPIC and PARADIGM development of an InP based generic photonic integration technology is being undertaken to implement complex InP based application-specific photonic integrated circuits (ASPIC) with transmit and receive functionalities from a set of basic building blocks. The integration platform pursued at Fraunhofer HHI is building on semi-insulating substrate. Recently a variety of receiver-type PIC with up to 40 GHz bandwidth capability designed by external users was fabricated in multi-project wafer runs. Examples are demonstrated. Extension of this platform to include transmit functionalities is underway using an MOVPE based butt-coupling approach.
