Abstract

Embodiments described herein may be related to apparatuses, processes, and techniques related to coherent optical receivers, including coherent receivers with integrated all-silicon waveguide photodetectors and tunable local oscillators implemented within CMOS technology. Embodiments are also directed to tunable silicon hybrid lasers with integrated temperature sensors to control wavelength. Embodiments are also directed to post-process phase correction of optical hybrid and nested I/Q modulators. Embodiments are also directed to demultiplexing photodetectors based on multiple microrings. In embodiments, all components may be implements on a silicon substrate. Other embodiments may be described and/or claimed.
