Краткое описание

This work describes research and development of a superconducting nanowire single-photon detector (SNSPD) integrated with a parabolic mirror fabricated in a silicon wafer by focused ion beam etching. Using finite-difference time-domain simulations of the electromagnetic field distribution within the mirror and on its surface, the geometry of the molybdenum mirror was designed for efficient collection of light into a 1.5 µm spot. Reduction of the area of the SNSPD to 1.5 µm × 1.5 µm resulted in low kinetic inductance and faster operation. Although the detector response is currently limited by the 1 GHz band of the read-out electronics, the simulation suggests reduction of the detector dead time to 348 ps.
