Single photon avalanche diodes(SPADs) are devices that accurately time the detection of individual photons of light, with potential applications including LIDAR (3D mapping technology) for autonomous vehicles, as well as quantum key distribution (secure data encryption over optical fibre). The project will involve the design, fabrication and testing of GeSN SPAD detectors, operating from near to mid-infrared wavelengths. A number of applications require devices to work at wavelengths no greater than 1550 nm, but current technologies are extremely expensive. GeSn SPADs will allow NIR detection but at potentially low cost, due to compatibility with exisitng Si foundry infrastructure.

单光子雪崩二极管（SPAD）是一种能够准确地对单个光子的检测进行计时的器件，其潜在应用包括用于自动驾驶汽车的激光雷达（3D映射技术）以及量子密钥分发（光纤上的安全数据加密）。该项目将涉及GeSN SPAD探测器的设计、制造和测试，其工作波长从近红外到中红外。许多应用要求器件在不大于1550 nm的波长下工作，但目前的技术非常昂贵。GeSn SPAD将允许NIR检测，但由于与硅铸造基础设施的兼容性，成本可能较低。
