Bandwidth-enhanced superconducting nanowire single photon detectors for telecom wavelengths



Stephan Krapick, Marina Hesselberg, Varun B. Verma, Igor Vayshenker, Sae Woo Nam, Richard P. Mirin


We present a single-photon detector providing system detection efficiencies of at least (86.7 ± 0.9) % from 1450 nm to 1640 nm. It comprises bilayer superconducting WSi nanowires in conjunction with all-dielectric structures for optical impedance matching.
