Abstract: Embodiments comprise a system created through fabricating a lens array through which lasers are emitted. The lens array may be fabricated in the semiconductor substrate used for fabricating the lasers or may be a separate substrate of other transparent material that would be aligned to the lasers. In some embodiments, more lenses may be produced than will eventually be used by the lasers. The inner portion of the substrate may be formed with the lenses that will be used for emitting lasers, and the outer portion of the substrate may be formed with lenses that will not be used for emitting lasers—rather, through etching these additional lenses, the inner lenses may be created with a higher quality.

Abstract: A VCSEL array device formed of an array of raised VCSELs on an electrical contact and raised inactive regions connected to the electrical contact. The VCSELs can be physically and/or electrically organized to improve power or speed, or in phase and in parallel. The VCSELs and inactive regions are positioned between the electrical contact and an electrical waveguide. The VCSELs may be separated into subarrays and each VCSEL may be covered with an integrated or bonded microlens for directing beams of light without external lenses. The VCSELs may also be electrically selected to form two or more groups, with beams of light from each group have unique divergences, unique power or unique optical power, and each beam of light in a group forming a spot at a point on a line, on the same optical axis, or as part of a pattern.
