Near infrared photon detectors using titanium-based superconducting transition-edge sensors

摘要

Transition edge sensor (TES) detectors are showing great promise as single photon detectors in quantum information [1] and as fast bolometers in astronomical applications [2]. In the near infrared/optical range TESs offer good broadband quantum efficiency, high time resolution, and modest energy resolution. Therefore TESs provide the potential capabilities for the study of rapidly varying compact object systems. We are developing Ti-based TES as optical/near-infrared photon detectors [3].
