MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517078261 A) filed by Uality Quantum Photonics Ltd., Bristol, U.K., on Aug. 18, for 'single-photon triggered optical switches and/or optical signal routers.'
Inventor(s) include Laing, Anthony; Mccutcheon, Dara; Politi, Alberto; Rosenfeld, Lawrence; and Wakefield, Ross.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "Optical switching using an optical resonator into and out of which travelling optical modes (4), of a given optical signal frequency, to selectively couple by electro-optically modulating the resonance characteristics (e.g., resonance optical frequency) of the optical resonator (12) in response to a signal produced by the single-photon detector (20). The detection of a photon (27B) controls how (and when) the travelling optical modes couple into and/or out of the optical resonator. In this way, the route of travelling optical modes of light may be switched in response to (i.e., condition upon) the detection of a single photon."
The patent application was internationally filed on Feb. 22, 2024, under International application No.PCT/EP2024/054507.
