Paper Abstract
Single-photon detectors are the best option for applications where low noise measurements and/or high timing
resolution are required. At wavelengths between 900 nm and 1700 nm, however, low noise detectors have typically
been based on cryogenic superconducting technology, precluding their extended use in industrial or clinical
applications. Here we present a practical (i.e. compact, reliable and affordable) detector, based on a negative
feedback InGaAs/InP avalanche photodiode and exhibiting dark counts < 1 count-per-second at 10% efficiency, and
with efficiencies of up to 27%. We show how this detector enables novel applications such as singlet-oxygen
luminescence detection for Photo Dynamic Therapy (PDT) but can be an enabling technology also for a diverse set
of applications in both quantum communication (e.g. long-distance quantum key distribution) and biomedical
imaging.
