Abstract

Numerical optimization was performed via COMSOL to maximize p-polarized absorptance and p-to-s polarized absorptance ratio - nominated as polarization contrast - of superconducting nanowire single photon detectors (SNSPDs). Four different types of SNSPDs were integrated with various plasmonic structures capable of influencing the polarized light absorptance inside the superconducting nanowires. Half- and one-wavelength-scaled periodic structures were appropriate to initiate unique nanophotonical phenomena. Here we present that 95.1% absorptance and 1.8 □1013 polarization contrast can be achieved and show conditional polarization contrasts reachable by meeting criteria regarding the minimal ppolarized absorptance.
