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 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.

Abstract: A substrate comprises multiple interposers. Each interposer includes interposer elements, where an optical device is coupled to at least some of the interposer elements; two passages formed through the interposer, where each passage is registered with respect to the interposer elements; two blind holes formed in a surface of the interposer, where each blind hole is concentric with a different passage; two annular troughs formed in the surface, each concentric with a different passage, and an annular area separates the annular troughs from an outer diameter of the corresponding concentric passage; and two spherical registration elements, where each registration element is positioned on uncured adhesive on one of the annular areas, where the passages enable a vacuum to be drawn through such that the registration elements are pulled toward the surface of the interposer to self-align to the inner diameter of the blind holes.
