摘要： 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.

摘要： Embodiments described herein may be related to apparatuses, processes, and techniques related to fully integrated optical coherent modulators on a silicon chip. These coherent modulators may be used to enable transmitters, receivers, transceivers, tunable lasers and other optical or electro-optical devices to be integrated on a silicon chip. In embodiments, the optical coherent modulators may be based on differential microring modulators that may be nested in a Mach-Zehnder Interferometer (MZI) configuration. Embodiments may also be directed to a miniaturized and fully integrated coherent modulators, which can enable terabit per second (Tbps) transceivers in a small form factor based on coherent modulation on a silicon chip. Other embodiments may be described and/or claimed.
