Latest Patents

Perrenoud holds a patent for a "Device and system for single photon detection using a plurality of superconducting detection means connected in parallel." This device comprises two superconducting detectors, a bias-current source, a filter element, and a readout circuit. Each detector forms a detection area for the absorption of incident photons and is connected in parallel. The detectors are maintained below their critical temperature and are provided with an electrical bias current situated close to and below their critical current. This configuration allows the detectors to transition from a non-resistive state to a resistive state upon photon absorption, enabling the readout circuit to sense voltage changes corresponding to each photon event. The device also includes a current-redistribution portion to manage current density effectively.
