Abstract: A high contrast grating optoelectronic apparatus includes an optoelectronic device at a front surface of a substrate. The optoelectronic device is to one or both of emit light and detect light through a back surface of the substrate opposite the front surface. A high contrast grating (HCG) lens is adjacent to and spaced apart from the back surface of the substrate by a spacer. The spacer includes one or both of a wafer-bonded substrate and a cavity. The HCG lens is to focus the light.

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: A vertical-cavity surface-emitting laser (VCSEL) includes a 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 by the VCSEL through the substrate. The VCSEL lases in a single transverse mode.
