This project will develop a new commercial single photon avalanche detector (SPAD) platform for the important SWIR,MWIR and LWIR spectral ranges (1.7 - 12um). Conventional, many photon, photodiodes have been developed to providecomprehensive coverage of the IR spectrum and in doing so have enabled a multitude of important photonic applicationsand industries. As researchers and industry look to apply emerging quantum photonics, it is evident that available detectortechnology is limiting the spectral ranges which can be exploited. Visible and IR applications below a wavelength of 1.7um,are supported by existing Silicon and InP/InGaAs SPAD technologies. However, beyond these wavelengths there are noSPAD technologies available and hence no single photon detectors that offer their speed of response, high operatingtemperature and compact size, which are essential attributes for commercial viability.The detector to be developed and prototyped in this project employs a novel barrier based structure, proprietary toAmethyst Research Ltd. In recent years such barrier based structures have delivered leading performance metrics in manyphoton IR detectors. The Amethyst barrier technology uniquely allows the barrier detector concept to be extended byexciting internal avalanche gain, as exploited in SPADs. Preliminary characterisation at Lancaster University hasdemonstrated this and shown the potential for the new family of SPAD detectors.The project has the following milestonesMilestone 1: Design of Single Photon Quantum Avalanche Photo Diode (APD) based on Unipolar Barrier Detector (UBD)architecture (Amethyst Research and Lancaster University)Milestone 2: MBE Growth of the Quantum APD Structure (Lancaster University)Lancaster University have vast experience in growing III-V related semiconductor materials. Hence, for this program, theAPD structure will be grown at Lancaster University.Milestone 3: Quantum APD Fabrication (CST)Devices will be processed from wafer grown in Milestone 2 using state-of-the-art cleanroom facilities at CompoundSemiconductor Technologies (CST).Milestone 4: Quantum APD Testing and Sub-System Integration (Amethyst Research, Lancaster University andsubcontracted system OEMs)

该项目将开发一个新的商业单光子雪崩检测器（SPAD）平台，用于重要的SWIR，MWIR和LWIR光谱范围（1.7-12UM）。已经开发了许多传统的光子，光电二极管，以提供红外光谱的覆盖范围，并因此实现了许多重要的光子应用和行业。随着研究人员和行业希望应用新兴的量子光子学，很明显，可用的检测技术正在限制可以利用的光谱范围。现有的硅和INP/INGAAS SPAD技术支持了低于1.7UM波长的可见和IR应用。但是，除了这些波长之外，还有NOSPAD技术可用，因此，没有单个光子检测器提供其响应速度，高操作型和紧凑的尺寸，这是商业可行性的重要属性。在此项目中，要在此项目中开发和原型的探测器，这些探测器基于新颖的结构，这些障碍物是基于新颖的结构，这些效果是基于较近期的IRERISS，在这些障碍物中提供了这些范围。探测器。紫水晶屏障技术独特地允许通过Spads剥削的内部雪崩收益来扩展屏障探测器概念。兰开斯特大学的初步表征对此进行了示意，并显示了新的SPAD探测器家族的潜力。该项目具有以下里程碑式探测器1：基于Unipallar屏障探测器（UBD）的单层量子障碍二极管（APD）的设计（UBD）建筑（Unandyst Resuction and Lancystermentaper）（LancyStenter）（Lancystement）（Lancystermental）2：Milest lancements 2：Milest lancement op lancy land op lancy ap：lancy lancy ap：在增长III-V相关的半导体材料方面具有丰富的经验。因此，对于该计划，将在兰开斯特大学（Lancaster University）生长。米勒斯通（Milestone）3：量子APD制造（CST）设备将使用在“ Milestone 2”中使用最先进的清洁室设施在Goledsemedsmentoductotor技术（CST）中进行的晶圆处理。 OEM）
