Patent number: 11088509Abstract: A semiconductor vertical light source includes upper and lower mirrors with an active region in between, an inner mode confinement region, and an outer current blocking region that includes a common epitaxial layer including an epitaxially regrown interface between the active region and upper mirror. A conducting channel including acceptors is in the inner mode confinement region. The current blocking region includes a first impurity doped region with donors between the epitaxially regrown interface and active region, and a second impurity doped region with acceptors between the first doped region and lower mirror. The outer current blocking region provides a PNPN current blocking region that includes the upper mirror or a p-type layer, first doped region, second doped region, and lower mirror or an n-type layer. The first and second impurity doped region force current flow into the conducting channel during normal operation of the light source.Type: GrantFiled: January 7, 2020Date of Patent: August 10, 2021Assignee: University of Central Florida Research Foundation, Inc.Inventor: Dennis G.

Patent number: 11088510Abstract: A fabrication sequence for an oxide-confined VCSEL includes the deposition of a protective coating over exposed horizontal surfaces to prevent unwanted oxide layers from being formed during the lateral oxidation process used to create the oxide aperture. By preventing the oxidation of these surfaces in the first instance, the opportunity for moisture to gain access to the active region of the VCSEL is eliminated. For example, exposed Al-containing surfaces are covered with a protective coating of dielectric material prior to initiating the conventional lateral oxidation process used to form the oxide aperture of the VCSEL. With the protective coating in place, a conventional fabrication process is resumed, and the protective coating ultimately forms part of the passivation layer used to provide electrical isolation for the final VCSEL device.Type: GrantFiled: November 5, 2019Date of Patent: August 10, 2021Assignee: II-VI Delaware, Inc.Inventors: Lukas Mutter, Norbert Lichtenstein
