Superconducting Nanowire Single-Photon Detection (SNSPD) System

Background
The Air Force Research Laboratory (AFRL) at Wright-Patterson Air Force Base is conducting advanced research to support defense mission applications, including ladar (laser detection and ranging), laser communications, intelligence, surveillance, reconnaissance (ISR), and remote sensing systems.

The goal of this contract is to acquire a Superconducting Nanowire Single-Photon Detection (SNSPD) System that can detect and characterize extremely low levels of light, including single-photon events across visible and near-infrared wavelengths. Current technologies are limited in sensitivity and performance, necessitating the advancement provided by SNSPDs.

Incumbent Analysis (see Incumbents section for more detail)
This opportunity appears to have a closely related prior contract, FA875124P0046, awarded to Single Quantum USA for a “Superconducting Nanowire Single Photon Detection (SNSPD) System (rack-mount)” valued at $382,250 (08/26/24–05/26/25). The current requirement similarly calls for a complete SNSPD system with fiber-coupled inputs, readout electronics, and cryogenic closed-cycle cooling suitable for single-photon detection across visible to near-infrared wavelengths. The rack-mount SNSPD system work appears to be a direct continuation of procuring an integrated detector system for the same underlying sensing and characterization use cases.
