Integrated optical platform for photon-number resolving telecom-band detectors for photonic information processing
We report the development of the optical substrates for the demonstration of an integrated photon-number-resolving detector, operating in the telecom band at 1550 nm, employing an evanescently coupled design that allows it to be placed at arbitrary locations within a planar circuit. Up to five photons are resolved in the guided optical mode via absorption from the evanescent field into a tungsten transition-edge sensor. The detection efficiency is 7.2 ± 0.5%. The polarization sensitivity of the detector is also demonstrated.

Abstract

We report the development of the optical substrates for the demonstration of an integrated photon-number-resolving detector, operating in the telecom band at 1550 nm, employing an evanescently coupled design that allows it to be placed at arbitrary locations within a planar circuit. Up to five photons are resolved in the guided optical mode via absorption from the evanescent field into a tungsten transition-edge sensor. The detection efficiency is 7.2 ± 0.5%. The polarization sensitivity of the detector is also demonstrated.
