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)

该项目将开发一种新的商业单光子雪崩探测器（SPAD）平台，用于重要的SWIR，MWIR和LWIR光谱范围（1.7 - 12 μ m）。传统的，许多光子，光电二极管已被开发出来，以提供红外光谱的覆盖范围，并在这样做，使许多重要的光子应用和行业。随着研究人员和工业界希望应用新兴的量子光子学，很明显，现有的探测器技术限制了可以利用的光谱范围。现有的硅和InP/InGaAs SPAD技术支持波长低于1.7 μ m的可见光和红外应用。然而，在这些波长之外，没有可用的SPAD技术，因此没有单光子探测器提供其响应速度、高操作温度和紧凑尺寸，这是商业可行性的基本属性。在该项目中开发和原型化的探测器采用了一种新型的基于屏障的结构，近年来，这种基于屏障的结构在多光子红外探测器中提供了领先的性能指标。Amethyst势垒技术独特地允许势垒探测器概念通过激发内部雪崩增益而扩展，如SPAD中所利用的。在兰开斯特大学的初步表征已经证明了这一点，并显示了SPAD探测器新系列的潜力。该项目有以下里程碑：里程碑1：基于单极势垒探测器（UBD）架构的单光子量子雪崩光电二极管（APD）的设计（紫水晶研究和兰开斯特大学）里程碑2：量子APD结构的MBE生长（兰开斯特大学）兰开斯特大学在生长III-V族相关半导体材料方面拥有丰富的经验。因此，对于该计划，APD结构将在兰开斯特大学生长。里程碑3：量子APD制造（CST）器件将使用CompoundSemiconductor Technologies（CST）最先进的洁净室设施从里程碑2中生长的晶圆进行加工。里程碑4：量子APD测试和子系统集成（Amethyst Research，兰开斯特大学和分包系统OEM）
