We have measured the quantum efficiency (QE), GHz counting rate, jitter, and noise-equivalent power (NEP) of nanostructured NbN superconducting single-photon detectors (SSPDs) in the visible to infrared radiation range. Our 3.5-nm-thick and 100- to 200-nm-wide meander-type devices (total area 10 × 10 μm2), operating at 4.2 K, exhibit an experimental QE of up to 20% in the visible range and ∼10% at 1.3 to 1.55 μm wavelength and are potentially sensitive up to midinfrared (∼10 μm) radiation. The SSPD counting rate was measured to be above 2 GHz with jitter <18 ps, independent of the wavelength. The devices' NEP varies from ∼10-17 W/Hz½ for 1.55 μm photons to ∼10-20W/Hz½ for visible radiation. Lowering the SSPD operating temperature to 2.3 K significantly enhanced its performance, by increasing the QE to ∼20% and lowering the NEP level to ∼3 × 10-22 W/Hz½, both measured at 1.26 μm wavelength.
