  • METHOD OF FABRICATING A RESONANT CAVITY AND DISTRIBUTED BRAGG REFLECTOR MIRRORS FOR A VERTICAL CAVITY SURFACE EMITTING LASER ON A WING OF AN EPITAXIAL LATERAL OVERGROWTH REGION
    Publication number: 20240079856
    Abstract: A method for fabricating a quality and manufacturable aperture for light emitting elements, such as vertical cavity surface emitting lasers (VCSELs), using epitaxial later overgrowth (ELO). A bar comprised of island-like III-nitride semiconductor layers is grown on a substrate using a growth restrict mask, and the island-like III-nitride semiconductor layers are fabricated into light-emitting resonating cavities across a smallest length of the bar. Apertures for the resonating cavities are also fabricated along the smallest length of the bar on wing regions of the epitaxial lateral overgrowth. Distributed Bragg reflectors (DBRs) are fabricated as mirrors for the resonant cavities on the bottom and top of the wing regions of the epitaxial lateral overgrowth.
