  • Trench process for dense VCSEL design
    Patent number: 11876348
    Abstract: Trenched VCSEL emitter structures are described. In an embodiment, an emitter structure includes a cluster of non-uniformly distributed emitters in which each emitter includes an inside mesa trench and an oxidized portion of an oxide aperture layer extending from the inside mesa trench. An outside moat trench is located adjacent the inside mesa trench and is formed to a depth past the oxide aperture layer.
