ABSTRACT

InP membranes have appeared in the last decade as a viable integrated photonics platform, suitable for adding
photonic functions to silicon electronics. It combines the strengths of silicon photonics (high index contrasts and
therefore small footprint devices) with those of generic InP-platforms (monolithic integration of active and
passive devices). A range of functionalities has been developed on this platform, which goes by the name of
IMOS (Indium phosphide Membrane on Silicon). Competitive performances have been demonstrated for lasers,
fast detectors, waveguides, filters, couplers, modulators etc. The present contribution describes the recent
developments in this platform regarding the technology and results. Among the latest results are record low
propagation losses, improved input/output grating couplers, a variety of laser structures and improved
wavelength demuliplexers These developments demonstrate that IMOS has a high potential to deliver photonic
integrated circuits to a wide variety of application fields, e.g. telecom, datacom, sensing, terahertz and many
others.
