abstract="We report our studies on the spectral sensitivity of superconducting NbN thin-film single-photon detectors (SPD{\textquoteright}s) capable of GHz counting rates of visible and near-infrared photons. In particular, it has been shown that a NbN SPD is sensitive to 1.55-{\textmu}m wavelength radiation and can be used for quantum communication. Our SPD{\textquoteright}s exhibit experimentally measured intrinsic quantum efficiencies from 20{\%} at 800 nm up to 1{\%} at 1.55-{\textmu}m wavelength. The devices demonstrate picosecond response time (<100 ps, limited by our readout system) and negligibly low dark counts. Spectral dependencies of photon counting of continuous-wave, 0.4-{\textmu}m to 3.5-{\textmu}m radiation, and 0.63-{\textmu}m, 1.33-{\textmu}m, and 1.55-{\textmu}m laser-pulsed radiations are presented for the single-stripe-type and meander-type devices.",
