(author) In this paper several designs to maximize the absorption efficiency of superconducting-nanowire single-photon detectors are investigated. Using a simple optical cavity consisting of a gold mirror and a SiO<sub>2</sub> layer, the absorption efficiency can be boosted to over 97%: this result is confirmed experimentally by the realization of an...
