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: An array of monolithic wavelength division multiplexing (WDM) vertical cavity surface emitting lasers (VCSELs) with spatially varying gain peak and Fabry Perot wavelength is provided. Each VCSEL includes a lower distributed Bragg reflector (DBR), a Fabry Perot tuning/current spreading layer, and a structure comprising a multiple quantum well (MQW) layer sandwiched between a lower separate confinement heterostructure (SCH) layer and an upper SCH layer. The structure is sandwiched between the DBR and the Fabry Perot tuning/current spreading layer. Each MQW experiences a different amount of quantum well intermixing and concomitantly a different wavelength shift. Each VCSEL further includes a top mirror on the Fabry Perot tuning/current spreading layer. A method is also provided for manufacturing the array.
