  • Mode control in vertical-cavity surface-emitting lasers
    Patent number: 10381803
    Abstract: Aspects of the subject disclosure may include, for example, a first distributed Bragg reflector, a second distributed Bragg reflector, an active region with an oxide aperture between the first and second distributed Bragg reflectors, and a dielectric layer, where a positioning of the dielectric layer with respect to the first and second distributed Bragg reflectors and the oxide aperture causes suppression of higher modes of the vertical-cavity surface-emitting laser device. Other embodiments are disclosed.
    Type: Grant
    Filed: August 15, 2017
    Date of Patent: August 13, 2019
    Assignee: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOIS
    Inventors: John Michael Dallesasse, Benjamin Kesler, Thomas O'Brien, Jr.
