Publication number: 20230350130Abstract: A system and method for delivering stable light to a remote location are provided. The method includes splitting a laser beam generated by a laser into a reference beam and a delivery beam. The delivery beam is coupled into an optical fiber for delivery to the remote location. A reflected portion of the delivery beam comes back as a reflected delivery beam from the remote location through the optical fiber. An interference beam is generated by combining the reference beam and the reflected delivery beam. A phase difference between the reference beam and the reflected delivery beam is detected in order to adjust a phase of the laser beam based on the phase difference to reverse a phase shift of the delivery beam induced by noise added to the delivery beam while the delivery beam is transmitted through the optical fiber.Type: ApplicationFiled: March 20, 2023Publication date: November 2, 2023Applicant: Stable Laser Systems, Inc.Inventors: Josue DAVILA-RODRIGUEZ, William David LEE

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. Diddams, Jose Aumentado
