Kami melaporkan tentang peningkatan kecekapan pengesanan sistem dalam pengesan foton tunggal wayar nano superkonduktor (SNSPD) dengan menggunakan struktur rongga optik. Kawat nano dibuat menggunakan filem nipis NbN setebal 4-nm dan ditutup dengan rongga SiO dan cermin Au yang direka untuk panjang gelombang 1300-1600 nm. Peranti ini dipasang ke dalam pakej berganding gentian, dan dipasang dalam sistem berbilang saluran praktikal berdasarkan cryocooler GM. Kecekapan pengesanan sistem bergantung pada penyerapan struktur rongga, dan masing-masing mencapai 28% dan 40% pada panjang gelombang 1550 nm dan 1310 nm. Nilai ini jauh lebih tinggi daripada SNSPD tanpa rongga optik.

Abstract: We report on the enhancement of system detection efficiency in a superconducting nanowire single-photon detector (SNSPD) by applying the optical cavity structure. The nanowire was made using 4-nm-thick NbN thin films and covered with an SiO cavity and Au mirror designed for 1300-1600 nm wavelengths. The device is mounted into fiber-coupled packages, and installed in a practical multichannel system based on GM cryocoolers. System detection efficiency depends on the absorptance of cavity structure, and reached 28% and 40% at 1550 nm and 1310 nm wavelengths, respectively. These values were considerably higher than an SNSPD without optical cavity.
