    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: In example implementations of a vertical-cavity surface-emitting laser (VCSEL), the VCSEL includes a p-type distributed Bragg reflector (p-DBR) layer end a p-type ohmic (p-ohmic) contact layer adjacent to the p-DBR layer. The p-DBR layer may include an oxide aperture and the p-ohmic contact layer may have an opening that is aligned with the oxide aperture. The opening may be filled with a dielectric material. A metal layer may be coupled to the p-ohmic contact layer and encapsulate the dielectric material.

    Abstract: Examples herein relate to a Wavelength Division Multiplexing (WDM) optical module configured for M optical fibers, N WDM wavelengths and M×N optical signals. The module comprises an active silicon interposer, the interposer comprises a (M/2)×N array of photodetectors established on a front side of the interposer and N chips for the N WDM wavelengths. Each chip comprises M lenses for M optical signals, the M lenses established on a back side of a GaAs substrate, the M lenses comprising a first group of M/2 lenses to focus M/2 optical input signals onto M/2 photodetectors of the (M/2)×N array, and a second group of M/2 lenses to collimate M/2 optical output signals, and M/2 Vertical Cavity Surface Emitting Lasers (VCSELs) established on a front side of the GaAs substrate to generate the M/2 optical output signals.

    Abstract: Examples described herein relate to an optical device that entails phase shifting an optical signal. The optical device includes an optical waveguide having a first semiconductor material region and a second semiconductor material region formed adjacent to each other and defining a junction therebetween. Further, the optical device includes an insulating layer formed on top of the optical waveguide. Moreover, the optical device includes a III-V semiconductor layer formed on top of the insulating layer causing an optical mode of an optical signal passing through the optical waveguide to overlap with the first semiconductor material region, the second semiconductor material region, the insulating layer, and the III-V semiconductor layer thereby resulting in a phase shift in the optical signal passing through the optical waveguide.
