Mark R. Malonson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Tunable VCSEL polarization control through dissimilar die bonding
    Patent number: 10951009
    Abstract: A design and method for introducing asymmetric crystal strain to control polarization in a tunable VCSEL, either optically or electrically pumped. The invention is especially relevant to wafer- or die-bonded tunable VCSELs. Then, mechanical stress is applied to the half VCSEL device by asymmetric arrangement of metal bond pads.
    Type: Grant
    Filed: May 10, 2019
    Date of Patent: March 16, 2021
    Assignee: Excelitas Technologies Corp.
    Inventors: Bartley C. Johnson, Mark R. Malonson, Walid A. Atia, Mark E. Kuznetsov, James W. Getz, Peter S. Whitney

  • Reflector for directing front facet light to monitor diode
    Patent number: 6459710
    Abstract: A semiconductor laser system includes a reflector on the lid that directs light emitted from the front facet to the monitoring diode. Thus, even when the diode is installed behind the semiconductor laser chip, and as a result receives back facet light, the ratio of front facet to back facet light received by the monitoring diode is increased due to the operation of the reflector. This configuration improves power tracking in Bragg grating stabilized semiconductor laser systems, for example.
