Monolithically Integrated CMOS-Compatible III-V on Silicon Lasers

CMOS-compatible III-V lasers integrated on silicon are a crucial step to reduce power consumption and cost for next-generation optical transceivers. Here, we demonstrate a concept to co-integrate III-V lasers into a CMOS Silicon Photonics platform, in which lasers, photonics, and electronic circuitry share the same back end of line. Based on a bonded III-V epitaxial layer stack, ultra-thin laser devices, optically pumped lasing and coupling to silicon are demonstrated. Furthermore, we present all building blocks for electrically pumped laser devices.
