Description
Summary:Full‐Stokes polarimeters, equipped with the capability of discriminating light polarization states, can find important applications in various optical and optoelectronic devices. Nevertheless, currently most full‐Stokes polarimeters require complex and bulky optical elements or optical metasystems integrated with metasurfaces, which can increase the cost and cause energy loss. Here, the anisotropy of chiral 2D perovskite single crystals is explored and the full‐Stokes polarimeter based on pure chiral 2D perovskite single crystals is reported. By using optical anisotropy and the ability to distinguish the helicity of the circularly polarized light, chiral 2D perovskite polarimeter integrates the polarizer, waveplate, and photodetector together and thus can be able to discriminate the polarization states of light. The as‐fabricated device exhibits a photoresponsivity of 0.136 A W−1 and a detectivity of 1.2 × 1010 Jones. This study provides a paradigm to construct filterless on‐chip Stokes polarimeter with great simplicity and low cost. On‐chip filterless full‐Stokes polarimeter is successfully demonstrated based on chiral 2D perovskite single crystals at room temperature, which equips with chirality and optical anisotropy. This approach provides a simple technique to achieve full‐Stokes parameter detection with low cost and great simplicity for optoelectronics and spintronic applications.
