Abstract

Photon number resolving transition-edge sensors (TES) are the cutting-edge enabling technology for high quantum efficiency photon counting when the number of photons of an input state needs to be determined. The TES developed at NIST reliably show system detection efficiencies of more than 95%, and even approach 99% for individual detectors. Recently, efforts to directly tying existing optical power measurements to measurements at the single-photon level are being considered by some metrology institutions around the world with the goal of better uncertainties. An initial step in this direction would be to explore how far existing detectors can be extended beyond their usual operating regimes. One promising candidate under consideration for connecting these two regions is the TES, as it functions as a microcalorimeter and is therefore able, in principle, to measure optical powers from the single-photon-regime to picowatt levels.
