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.

Abstract: An apparatus includes a first and second VCSEL, each with an integrated lens. The VCSELs emit a first light beam having first optical modes at first wavelengths and a second light beam having second optical modes at second wavelengths. The apparatus also has an optical block with a first and second surface, a mirror coupled to the second surface, and a wavelength-selective filter coupled to the first surface. The first integrated lens mode matches the first beam to the optical block, and the second integrated lens mode matches the second beam to the optical block such that the first beam and second beam each have substantially a beam waist with a beam waist dimension at the first and second input region, respectively. An exit beam that includes light from the first beam and the second beam is output from the second surface of the optical block.

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: A vertical-cavity surface-emitting laser (VCSEL) includes first reflector having a first reflectivity; a second reflector having a second reflectivity, where the second reflectivity is less than the first reflectivity; a gain region between the first and second reflectors; and a substrate having a first surface and a second surface, where the first surface is coupled to the second reflector, and where the second surface is formed into a lens to act upon light emitted the VCSEL through the substrate. The VCSEL lases in a single transverse mode.
