Illumination direction dependence of NbN absorptance in p-pitch and P-pitch integrated devices, (aa,ba) NCAI-SNSPD; (ab,bb) NCDAI-SNSPD; (ac,bc) NCDDAI-SNSPD, and (ad,bd) NCTAI-SNSPD illuminated by 1550 nm p-polarized light. Comparison of polar angle dependent NbN absorptances in S-orientation of (a) p = 264 nm; (b) P = 792 nm periodic integrated SNSPDs illuminated by p-polarized light.
