Circularly polarised light will revolutionise emerging technologies, including encrypted light-based communications, quantum computing, bioimaging and multi-channel data processing. In order to make use of these remarkable opportunities, high performance photodetectors that can accurately differentiate between left- and right-handed circularly polarised light are desperately needed. Whilst this potential has resulted in considerable research interest in chiral materials and circularly polarised photodetecting devices, their translation into real-world technologies is limited by non-standardised reporting and testing protocols. This mini-review provides an accessible introduction into the working principles of circularly polarised photodetectors and a comprehensive overview of the performance metrics of state-of-the-art devices. We propose a rigorous device characterisation procedure that will allow for standardised evaluation of novel devices, which we hope will accelerate research and investment in this area.
圆偏振光将彻底改变新兴技术，包括基于光的加密通信、量子计算、生物成像和多通道数据处理。为了利用这些绝佳机遇，迫切需要能够精确区分左旋和右旋圆偏振光的高性能光电探测器。尽管这种潜力引发了对手性材料和圆偏振光电探测器件的大量研究兴趣，但它们向实际技术的转化受到非标准化报告和测试协议的限制。本综述简要介绍了圆偏振光电探测器的工作原理，并全面概述了最先进器件的性能指标。我们提出了一个严格的器件表征程序，该程序将允许对新型器件进行标准化评估，我们希望这将加速该领域的研究和投资。
