Helical-chiroptical nanowires generated orbital angular momentum for the detection of circularly polarized light

Abstract

In this work, we designed a type of organic chiral polymeric nanowire with strong orbital angular momentum to fabricate circularly polarized light detectors. In chiral polymeric nanowires, chirality induced orbital angular momentum could lead to the splitting of spin up and spin down energy levels, which determines the performance of circularly polarized light detection. In addition, chiral polymeric nanowire based circularly polarized light detectors exhibit excellent reversibility and stability after several hundred switching operations, which provides a solid footstone for potential applications.
