Cavity-integrated ultra-narrow Superconducting Nanowire Single-Photon Detector based on a thick niobium nitride film

摘要

We propose a design for cavity-integrated Superconducting Nanowire Single-Photon Detectors based on 20-nm-wide 10-nm-thick nanowires. Our simulations show that these detectors can potentially reach ∼90% device detection efficiency.
