Circularly polarized light detection has attracted growing attention because of its unique application in security surveillance and quantum optics. Here, through designing a chiral polymer as a donor, a high-performance circularly polarized light detector is fabricated, successfully enabling detection from ultraviolet (300 nm) to near-infrared (1100 nm). The chiroptical detector presents an excellent ability to distinguish right-handed and left-handed circularly polarized light, where dissymmetries in detectivity, responsivity, and electric current are obtained and then optimized. The dissymmetry in electric current can be increased from 0.18 to 0.23 once an external magnetic field is applied. This is a very rare report on the dissymmetry tunability by an external field in chiroptical detectors. Moreover, the chirality-generated orbital angular momentum is one of the key factors determining the performance of the circularly polarized light detection. Overall, the organic chiroptical detector presents excellent stability in detection, which provides great potential for future flexible and compact integrated platforms.

一种有机手性探测器，有利于从近红外到紫外的圆偏振光探测和磁场放大探测中的不对称性
圆偏振光检测因其在安全监控和量子光学中的独特应用而受到越来越多的关注。在这里，通过设计一种手性聚合物作为供体，制造了一种高性能的圆偏振光探测器，成功地实现了从紫外（300 nm）到近红外（1100 nm）的检测。手性光学探测器具有出色的区分右旋和左旋圆偏振光的能力，其中获得并优化了探测率、响应度和电流的不对称性。一旦施加外部磁场，电流的不对称性可以从 0.18 增加到 0.23。这是关于手性光学探测器中外场的不对称可调谐性的非常罕见的报告。而且，手性产生的轨道角动量是决定圆偏振光探测性能的关键因素之一。总的来说，有机手性检测器在检测中表现出优异的稳定性，为未来灵活紧凑的集成平台提供了巨大的潜力。
