Abstract
In this paper, we present a system for direct, time-resolved measurement of VIS and IR luminescence and phosphorescence, coupled with a large area, multimode optical fiber superconducting single-photon detector (SSPD). 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 SSPDs coupled to multimode fibers can be fabricated [1], and these detectors have been coupled with phosphorescence/fluorescence lifetime imaging microscopy (PLIM/FLIM) systems. These detectors aslo work in the visible range and have even higher efficiency in the near infrared, providing a wide range of applications for luminescence measurements.
