Sensitive singlet oxygen detection system based on a superconducting single photon detector

Year: 2026

Type: conference-paper

Abstract: In this paper we present a sensitive system for detecting photons of singlet oxygen phosphorescence combined with the superconducting nanowire single photon detector (SNSPD). Detector coupled with multimode fiber and efficiency above 80 % with working area 50x50 um2and dark counts rate at working point of 1000 Hz, optimized for measurements around 1270 nm. SSPDs outperform other single-photon detectors in terms of performance and may be the best choice for many applications, but their sensitive area is rather small, making them well suited for coupling to a single mode optical fiber. Research has shown that large-area SNSPDs coupled to multimode fibers can be fabricated, and these detectors have been coupled with phosphorescence/fluorescence lifetime imaging microscopy (PLIM/FLIM) systems.
