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 include apparatuses, methods, and systems including a laser device having a 1×3 MMI coupler within a semiconductor layer. A front arm is coupled to the MMI coupler and terminated by a front reflector. In addition, a coarse tuning arm is coupled to the MMI coupler and terminated by a first back reflector for coarse wavelength tuning, a fine tuning arm is coupled to the MMI coupler and terminated by a second back reflector for fine wavelength tuning, and a SMSR and power tuning arm is coupled to the MMI coupler and terminated by a third back reflector. A gain region is above the front arm and above the semiconductor layer. Other embodiments may also be described and claimed.
