Optimization of Plasmonic Structure Integrated Single-photon Detector Designs to Enhance Absorptance

Abstract

Plasmonic structure integrated superconducting nanowire single-photon detector (SNSPD) configurations were optimized for 1550 nm p-polarized light illumination to maximize absorptance. Orientation dependent NbN absorptance, spectral sensitivity and dispersion characteristics were investigated to find optimal configurations.

The GLOBAL Optimization Algorithm

“…The idea, and motivation, of reworking the algorithm came while we were working on an industrial designing task [16]. GLOBAL seemed the best tool to use, but we encountered a handful of issues.…”

Design and Development of Global Optimization Methods with Applications

“…The algorithmic design and the first implementation [13] are coming from an era when the hardware meant a serious limitation that researchers had to constantly consider. The idea of reworking the algorithm came around during an industrial, precision designing task [18]. GLOBAL was the best tool to use, but we had to over- We published my work as a part of a comprehensive book about GLOBAL [9] and also presented it in a conference [10] with Balázs Bánhelyi, Tibor…”
