Maturing a Novel Extended IR Single Photon Detector for Quantum Systems

量子通信系统需要能够捕获单光子的光子探测器，而量子成像需要能够调谐到特定光子能量的探测器阵列。我们将建立在第一阶段工作的基础上，该阶段工作提供了一种新的扩展红外单光子雪崩探测器(SPAD)技术的概念验证，该技术基于一种新的化合物半导体有源区。开发第二阶段的目标是进一步提高核心探测器平台的性能，生产成套的SPAD，将现有的单元素演示器扩大到2D SPAD阵列，并降低阵列集成的风险，以实现与行业相关的单光子成像子系统。该项目将整合现有的学术界、中小企业和产业界的联合体，由紫晶研究有限公司领导，与兰开斯特大学、CST和SELEX ES(作为分包商)合作。此外，我们还与赫里奥特·瓦特大学建立了伙伴关系，以评估该技术在先进的单光子探测应用中的应用，从而扩大了该项目的范围。

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.
