The present disclosure is directed to photonic wavelength division multiplexing (WDM) receivers with polarization diversity and/or low reflectance. In embodiments, a WDM receiver is provided with a splitter, a plurality of waveguides and a plurality of photodetectors in series. The waveguides having particular equal path lengths relationship from the splitter to respective ones of the photodetectors. In other embodiments, the WDM receiver is provided with a splitter, a looped waveguide, a plurality of photodetectors, and a plurality of variable optical attenuators (VOAs). The VOAs are configured to suppress reflection of signal beams back to the transmitter. In various embodiments, the WDM receiver is a receiver sub-assembly of a silicon photonic transceiver disposed in a silicon package. Other embodiments may be described and/or claimed.

Photonic wavelength division multiplexing (WDM) receiver with polarization diversity and/or low reflectance

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.
