    Abstract: Examples herein relate to polarization diversity optical interface assemblies including a single mode optical fiber and first and second grating couplers disposed on a substrate. The first and second grating couplers are coupled to first and second waveguides, respectively. The assemblies further includes an optical connector to couple light between the single mode optical fiber and each of the first and second grating couplers. The optical connector includes a ferrule and a walk-off crystal. The ferrule is coupled to a portion of the single mode optical fiber. The walk-off crystal is configured to spatially separate the light into first and second orthogonal polarization modes prior to passing through the respective first and second grating couplers and/or combine the first and second polarization modes of the light prior to passing through the single mode optical fiber.

    Abstract: In some examples a silicon photonic (SiPh) solder reflowable assembly may comprise a silicon interposer bonded to an organic substrate, the silicon interposer having an optical grating disposed on the interposer to couple an optical signal, a lens array chip, the lens array comprising one or more lenses on a wafer, the lens array chip flip chip reflowed to the silicon interposer by a bonding agent and the one or more lenses having a predetermined shape that expands, collimates, and tilts a beam of the optical signal exiting the grating. The wafer has a coefficient of thermal expansion (CTE) that matches silicon and the one or more lenses and the grating are aligned in such a way the optical signal enters the grating at a desired angle.

    Abstract: One example includes an optical transmitter system. The system includes a waveguide to receive and propagate an optical signal. The system also includes a ring modulation system comprising a ring resonator that is optically coupled to the waveguide and is to resonate a given wavelength of the optical signal in response to an input data signal that is provided to a modulation amplifier to provide carrier injection to change a refractive index of the ring resonator to resonate the given wavelength of the optical signal to modulate the optical signal. The system further includes a tuning controller associated with the ring modulation system. The tuning controller can implement iterative feedback tuning of the ring modulation system based on a relative amplitude of an optical intensity of the given wavelength in the ring resonator and a variable reference amplitude to substantially stabilize the ring resonator with respect to the given wavelength.

    Abstract: In one example, a device includes a photodetector to generate an electrical signal in response to an optical signal and a transimpedance amplifier unit to receive the electrical signal. In one example, the transimpedance amplifier unit may include a first inverter unit, a second inverter unit coupled to the first inverter unit, and a third inverter unit coupled to the second inverter unit. In one example the third inverter unit may include a feedback resistor and a first n-type transistor in parallel to the feedback resistor, where the first n-type transistor is to provide a variable gain of the third inverter unit.

    Abstract: An example system for multi-wavelength optical signal splitting is disclosed. The example disclosed herein comprises a first splitter, a second splitter, and a modulator. The system receives a multi-wavelength optical signal and an electrical signal, wherein the multi-wavelength optical signal comprises a plurality of optical wavelengths and has a power level. The first splitter is to split the plurality of optical wavelengths into a plurality of optical wavelength groups. The second splitter is to split the multi-wavelength optical signal or the plurality of optical wavelength groups into a plurality of lower power signal groups. The modulator is to encode the electrical signal into the plurality of optical wavelength groups, the plurality of lower power signal groups, or a combination thereof.

    Abstract: Examples described herein relate to a driver circuit. In an example, the circuit includes a first input for receiving a first signal and a second input for receiving a second signal that is an inverse of the first signal. The circuit also includes a first driver array electrically coupling the first input to a first DC isolator and a first delay tap line electrically coupling the second input to the first DC isolator. The circuit further includes a second driver array electrically coupling the second input to a second DC isolator and a second delay tap line electrically coupling the first input to the second DC isolator. A carrier controller of the circuit is electrically coupled between the first DC isolator and the second DC isolator.
