Abstract: An optical device, a method of configuring an optical device, and a method of using a fiber Bragg grating is provided. The optical device includes a fiber Bragg grating, a narrowband optical source, and at least one optical detector. The fiber Bragg grating has a power transmission spectrum as a function of wavelength with one or more resonance peaks, each comprising a local maximum and two non-zero-slope regions with the local maximum therebetween. The light generated by the narrowband optical source has a wavelength at a non-zero-slope region of a resonance peak that is selected such that one or more of the following quantities, evaluated at the resonance peak, is at a maximum value: (a) the product of the group delay spectrum and the power transmission spectrum and (b) the product of the group delay spectrum and one minus the power reflection spectrum.

Abstract: A superconducting nanowire single photon detector (SNSPD) device includes a substrate, a distributed Bragg reflector on the substrate, a seed layer of a metal nitride on the distributed Bragg reflector, and a superconductive wire on the seed layer. The distributed Bragg reflector includes a plurality of bi-layers, each bi-layer including lower layer of a first material and an upper layer of a second material having a higher index of refraction than the first material. The wire is a metal nitride different from the metal nitride of the seed material.
