Abstract: Embodiments include apparatuses, methods, and systems including a dynamic polarization controller (DPC) to receive a first light beam and a second light beam, to adjust a rotation of a state of polarization (SOP) of the first light beam and the second light beam to generate a third light beam and a fourth light beam, under the control of a first control signal, a second control signal, and a third control signal. The first control signal may be related to a phase difference between the third light beam and the fourth light beam, the second control signal may be related to an intensity difference between the third light beam and the fourth light beam, and the third control signal may be related to a rotation of a SOP of the third light beam and the fourth light beam. Other embodiments may also be described and claimed.

Abstract: Embodiments herein relate to an optical system coupled with or including a control logic. The control logic may be configured to identify, based on feedback provided by a photodiode (PD) of an optical receiver, that an amplitude of an optical marker signal output by an interferometer of the optical receiver is above a threshold value. The control logic may further be configured to adjust, based on the identification, a thermo-optic phase tuner of the interferometer, wherein adjustment of the thermo-optic phase tuner results in a change to the amplitude of the optical marker signal. Other embodiments may be described and/or claimed.

Abstract: 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.
