| description | This paper aims to survey the current state of single-photon detector technology,
and eventually focus on the superconducting nanowire single-photon detector
(SNSPD) as well as its operating mechanisms. The applications and factors
influencing its efficiency will be discussed. After evaluating the current challenges
faced in the research landscape with regards to improving detection efficiency, this
study will implement waveguides to facilitate a scalable, on-chip solution for ease
of fabrication of future SNSPD devices. Waveguide-integration will be the main
approach adopted within this paper in enhancing detection efficiency that respects
the principles of coherent perfect absorption. Subsequently, the waveguide will be
computationally optimized using a numerical analytic method known as the Finite Difference Time-Domain (FDTD) method. In the geometrical optimization of the
waveguide, the optimal transmission value was 99.02%. This was a 34% increase
from the non-optimized transmission value. Consequently, the optimization of the
nanowire detector and the eventual utilization of coherent perfect absorption is
discussed. |
