一种汇聚增强光响应超导单光子探测器及其制备方法
摘要：
本发明公开了一种汇聚增强光响应的超导单光子探测器及其制作方法，包括MgO衬底、超导单光子探测器、透明介质隔离层、金属反射层、透明介质层、金属阻挡环和金属光栅层。超导单光子探测器、透明介质隔离层、金属反射层、透明介质层和金属光栅层依次按照从下向上的顺序生长在MgO衬底上；金属阻挡环位于透明介质层的外围，并连接金属反射层和金属光栅层；金属光栅层为同心的金属多环结构；金属反射层为一个金属环与一个透明介质环组合而成，且两环同心。本发明通过将大面积范围内入射的信号光汇聚到很小面积的超导单光子探测器光敏面上来显著提升其响应，最大可提升30倍。
摘要（英）：

The invention discloses a converging enhancement photo-response superconductivity single photon detector and a preparing method thereof. The converging enhancement photo-response superconductivity single photon detector comprises a magnesium oxide (MgO) substrate, a superconductivity single photon detector, a transparent medium isolation layer, a metal reflecting layer, a transparent medium layer, a metal barrier layer and a metal grating layer. The superconductivity single photon detector, the transparent medium isolation layer, the metal reflecting layer, the transparent medium layer and the metal grating layer grow on the MgO substrate in sequence from the lower upward. The metal barrier layer is located on the periphery of the transparent medium layer, and connected with the metal reflecting layer and the metal grating layer. The metal grating layer is of a homocentric metal multi-loop structure. The metal reflecting layer is composed of a metal ring and a transparent medium ring, and the metal ring and the transparent medium ring are homocentric. The converging enhancement photo-response superconductivity single photon detector converges incident signal light in a large area scope onto a superconductivity single photon detector photosensitive surface with small area so as to observably improve responses of the superconductivity single photon detector, and can improve the responses by 30 times to the utmost.
