Patent number: 11742955Abstract: An operational environment is disclosed herein that includes a cryogenic environment and a signal source. The cryogenic environment includes a signal target, an optical link, signal converter devices, and an electrical link. Outside of the cryogenic environment, the signal source generates an electric signal. An electric-to-optical converter converts the electrical signal into an optical signal. The optical link delivers the optical signal into the cryogenic environment. Inside the cryogenic environment, an optical-to-electrical converter converts the optical signal back into an electrical signal. The optical-to-electrical converter transfers the electric signal to the signal target.Type: GrantFiled: May 11, 2022Date of Patent: August 29, 2023Assignees: The Regents of the University of Colorado, a body corporate, Government of the United States of America, as represented by the Secretary of CommerceInventors: Florent Lecocq, Josue Davila-Rodriguez, Franklyn John Quinlan, John Teufel, Scott A.
