Maturing a Novel Extended IR Single Photon Detector for Quantum Systems

Quantum communication systems require photon detectors that are capable of single photon capture, andquantum imaging requires detectors arrays that can be tuned to specific photon energies. We will build oninitial Phase 1 work which delivered a proof of concept demonstration of a novel extended infrared SinglePhoton Avalanche Detector (SPAD) technology, based on a novel compound semiconductor active region. Theobjective of Phase 2 of the development is to further improve the performance of the core detector platform,produce a packaged SPAD, scale up the existing single element demonstrator to a 2D SPAD array and de-riskarray integration towards an industry relevant single photon imaging sub-system. The project will consolidatethe existing consortia of academia, SME’s and industry led by Amethyst Research Ltd, in partnership withLancaster University, CST and Selex ES (as a subcontractor). In addition, we have extended the reach of theproject with an associate partnership with Heriot Watt University to evaluate the technology in advanced singlephoton detection applications.
