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 of the present disclosure include a tunable laser comprising an optical coupler to couple light between a first laser cavity and a second laser cavity. The first laser cavity may extending between the optical coupler and a first reflector and include a first gain section. The second laser cavity may extend between the optical coupler and a second reflector and including a second gain section. At least one of the first laser cavity and the second laser cavity is tunable.

Abstract: Examples herein relate to devices with optical ports in fan-out configurations. An electrical device may have a substrate with an electrical port on a first face of the substrate and a plurality of optical ports on a second face of the substrate. The plurality of optical ports may be positioned in a fan-out configuration on the second face of the substrate. The electrical device may also have an integrated circuit with an electrical connection and a plurality of optical connections. A first face of the integrated circuit may be coupled to the substrate. The electrical connection of the integrated circuit may be communicatively coupled to the electrical port of the substrate, and the plurality of optical connections may be communicated coupled to the plurality of optical ports of the substrate.

Abstract: One example includes an optical coupler. The optical coupler includes a waveguide formed in a first layer of a layered structure that is to propagate an optical signal. The waveguide includes an end portion. The optical coupler also includes a turning mirror that includes a bulk structure and a reflective material deposited on an angular face of the bulk structure to form a surface of the turning mirror. The bulk structure can have a greater cross-sectional size than a cross-sectional size of the waveguide, such that the angular face extends above the first layer of the layered structure and extends into a second layer of the layered structure below the first layer. The surface of the turning mirror can be arranged to reflect the optical signal that is provided from the end portion of the waveguide.
