  • Tailoring of high power VCSEL arrays
    Patent number: 12015245
    Abstract: Modification of the topology of selected regions of individual VCSEL devices during fabrication is utilized to provide an array output beam with specific characteristics (e.g., “uniform” output power across the array). These physical features include at least the width of the metal aperture, the width of the oxide aperture, and/or the geometry of the contact ring structure on the top of the VCSEL device. The modifications may also function to adjust the numerical apertures (NAs) of the devices, the beam waist, wallplug efficiency, and the like.
    Type: Grant
    Filed: February 15, 2023
    Date of Patent: June 18, 2024
    Assignee: II-VI Delaware, Inc.
    Inventors: Giuseppe Tandoi, Norbert Lichtenstein, Lukas Mutter, Andre Bisig
