    Abstract: Pluggable optical transceiver modules are described herein that are specifically configured to preclude use of fiber jumpers inside of the module. Pluggable optical transceiver modules implement a rigid-plane jumper that provides an opto-mechanical interface between an external fiber cable (attached to the pluggable optical transceiver module) and the optical transceiver in a manner that does not require the fiber jumper, while ensuring reduced optical loss. In some embodiments one or more rigid waveguide plates act as an opto-mechanical coupling between the external fiber cable and on-board opto-electrical components (e.g., optical transceiver). For example, the rigid waveguide plates are coupled to a faceplate connector, and a CWDM block that is in turn optically coupled to the optical socket. In some embodiments, the CWDM block is directly attached to the rigid waveguide plates. In some embodiments, the CWDM block is indirectly attached to the rigid waveguide plates using a half periscope.

    Abstract: In the examples provided herein, a system includes an input waveguide, where a first end of the input waveguide is coupled to a light-emitting optical transmitter to allow the emitted light to enter the input waveguide, and a first ring resonator tunable to be resonant at a first resonant wavelength, wherein the first ring resonator is positioned near the input waveguide to couple a light at the first resonant wavelength from the input waveguide to the first ring resonator. The system also has a bus waveguide positioned to couple the light at the first resonant wavelength in the first ring resonator to the bus waveguide, and a mechanism to wavelength-tune the first ring resonator to a particular wavelength.

    Abstract: A VCSEL device includes a substrate and a first DBR structure disposed on the substrate. The VCSEL device further includes a cathode contact disposed on a top surface of the first DBR structure. In addition, the VCSEL device includes a VCSEL mesa that is disposed on the top surface of the first DBR structure. The VCSEL mesa includes a quantum well, a non-circularly-shaped oxide aperture region disposed above the quantum well, and a second DBR structure disposed above the non-circularly-shaped oxide aperture region. In addition, the VCSEL mesa includes a selective polarization structure disposed above the second DBR structure and an anode contact disposed above the selective polarization structure.

    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 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.
