Current state-of-the-art free space laser links used for satellite communications are severely limited in speeds primarily due to the high power consumption of the optical transceivers. In this project we exploit recent breakthrough 3D monolithic integration of photonic structures, particularly high-speed graphene-silicon devices on CMOS electronics to create CMOS-compatible high-bandwidth transceivers for ultra-low power Terabit-scale optical communications. The new platform can enable implementation of graphene-silicon structures with unprecedented data modulation speeds, offering an optical space communications infrastructure within a compact power envelope.
