  • Surface-emitting ring-cavity quantum cascade laser with ring-shaped phase shifter and related methods
    Patent number: 9819150
    Abstract: A ring-cavity surface emitting quantum cascade laser (RCSE-QCL) may include a ring-shaped active region having first and second opposing facets. One of the first and second opposing facets may define a radiation emitting facet. The RCSE-QCL may also include a ring-shaped phase shifter aligned with the radiation emitting facet and having a spiraled surface.
    Type: Grant
    Filed: June 4, 2014
    Date of Patent: November 14, 2017
    Assignee: UNIVERSITY OF CENTRAL FLORIDA RESEARCH FOUNDATION, INC.
    Inventors: Robert E. Peale, Pedro Figueiredo, Andrey V. Muraviev

  • Quantum cascade laser with autonomously aligned external cavity and related methods
    Patent number: 9250130
    Abstract: A quantum cascade laser (QCL) may include a QCL crystal having an emitting facet, and an active region adjacent the emitting facet, the emitting facet for providing an electromagnetic beam. The QCL may include an optical cavity comprising a mirror being external to the QCL crystal, and for redirecting the electromagnetic beam into the active region of the QCL crystal to provide optical feedback, and a driver circuit for driving the QCL crystal with a constant current. The QCL may include a controller coupled to the optical cavity and for dynamically and autonomously aligning the optical cavity based upon an error signal from the QCL crystal to maintain stable the optical feedback into the active region of the QCL crystal.
