Multispectral and low-filling-factor superconducting nanowire single photon detector with high absorption efficiency

We propose a superconducting nanowire single photon detector (SNSPD) that can work efficiently at two target wavelengths and has a significant improvement in the counting rate due to the low-filling-factor nanowires in the silicon slots and the silver reflector. Numerical simulations show that the a...
