Emmanuel P. Supertzi 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).

  • Thallium arsenic sulfide crystals (t1.sub.3 AsS.sub.3) high efficiency nonlinear optical applications
    Patent number: 5563730
    Abstract: Crystals formed of Tl.sub.3 AsS.sub.3 provide very good materials for the nonlinear optical conversion efficiency. The crystals are useful in nonlinear optical devices such as harmonic generators and optical parametric oscillators, and in linear applications such as acousto-optical devices. The method of preparing such crystals is also disclosed.
    Type: Grant
    Filed: June 21, 1994
    Date of Patent: October 8, 1996
    Assignee: Northrop Grumman Corporation
    Inventors: Narsingh B. Singh, James P. McHugh, Emmanuel P. Supertzi, Tom Henningsen, Richard P. Storrick, Robert Mazelsky
  • Solid solution crystals of Tl.sub.3 AsSe.sub.3 and Tl.sub.3 AsS.sub.3 for high efficiency optical applications
    Patent number: 5510929
    Abstract: Crystals formed of a solid-solution of Tl.sub.3 AsSe.sub.3 and Tl.sub.1 AsS.sub.3 provide very good materials for the nonlinear optical conversion efficiency. The crystals are useful in nonlinear optical devices such as harmonic generators and optical parametric oscillators, and in linear applications such as acousto-optical devices. The method of preparing such crystals is also disclosed.
