Abstract

We present thorough measurements of the intrin- sic detection efficiency in the wavelength range from 350 to 2500 nm for meander-type TaN and NbN superconducting nanowire single-photon detectors with different widths of the nanowire.The width varied from70 nmto 130 nm. The open-beam configuration allowed us to accurately normalize measured spec- tra and to extract the intrinsic detection efficiency. For detectors from both materials the intrinsic detection efficiency at short wavelengths amounts at 100% and gradually decreases at wave- lengths larger than the specific cut-off wavelengths, which de- creaseswith the width of the nanowire. Furthermore, we showthat applying weakmagnetic fields perpendicular to the meander plane decreases the smallest detectable photon flux.
