Coupling schemes for heterogeneous integration of III-V membrane devices and silicon-on-insulator waveguides

We present and numerically analyze two schemes for efficient, large-bandwidth, and fabrication-tolerant optical coupling of bonded III-V membrane active components to an underlying nanophotonic waveguide circuit in silicon-on-insulator (SOI). Coupling of active membrane components to passive waveguides enables the integration of ultracompact passive waveguide circuits and active optoelectronic devices.
