Abstract
An apparatus includes a base layer; and a superconducting nanowire disposed on the base layer in a continuous meander pattern and including an amorphous metal-metalloid alloy such that the apparatus is configured to detect single photons, and the continuous meander pattern includes: a plurality of parallel line segments; and a plurality of curved segments, wherein adjacent parallel line segments are joined by a curved segment. A method for making an apparatus for detecting single photons includes forming a base layer; forming a superconducting layer on the base layer; patterning the superconducting layer; and forming a continuous meander pattern from the superconducting layer, the continuous meander pattern includes a plurality of parallel line segments; and a plurality of curved segments, wherein adjacent parallel line segments are joined by a curved segment; and forming a dielectric layer on the continuous meander pattern, the dielectric layer including a dielectric material that is substantially transparent to a predetermined photon wavelength, wherein the apparatus is configured to detect single photons.
