Detection of circularly polarized light (CPL) accelerates the development of various optical technologies, but the additional quarter-wave plate and linear polarizer are required for conventional polarized light detectors, resulting in tremendous difficulty in integration and miniaturization of the devices. Herein, we fabricate pure (010)-orientated chiral one-dimensional (1D) perovskite microwire arrays with high crystallinity, strict alignment, and homogeneous size by a capillary-bridge-manipulated method. By the synergy of the excellent crystallinity and pure crystallographic orientation, high-performance CPL photodetectors are fabricated, with a maximum anisotropy factor of 0.23, responsivity exceeding 26 mA W −1, and detectivity exceeding 2.2 × 1011 Jones. Furthermore, the CPL photodetectors based on microwire arrays also exhibit impressive environmental stability under ambient conditions.
