Abstract
We present the overview of our recent results in research and development of superconducting single-photon detector (SSPD) practical applications such as quantum cryptography. By optimization of fabrication process and usage of high-quality silicon wafers with SiO2 layer acting as a microcavity we managed to reach up to 35.6% detection efficiency at 1500 nm wavelength. Also we extended its wavelength range beyond 1800 nm by the usage of the fluoride ZBLAN fibres.
