Metasurface for oscillatory spin splitting along the optical path
文献摘要：
Spin splitting of light originates from the interplay between the polarization and spatial degrees of freedom as a fundamental constituent of the emerging spin photonics,providing a prominent pathway for manipulating pho-ton spin and developing exceptional photonic devices.However,previously relevant devices were mainly designed for routing monotonous spin splitting of light.Here,we realize an oscillatory spin splitting of light via metasur-face with two channel Pancharatnam-Berry phases.For the incidence of a linearly polarized light,the concomi-tant phases arising from opposite spin states transition within pathways of the metasurface induce lateral spin splitting of light with alternately changed transport direction during beam guiding.We demonstrate the invari-ance of this phenomenon with an analogous gauge transformation.This work provides a new insight on steering the photon spin and is expected to explore a novel guiding mechanism of relativistic spinning particles,as well as applications of optical trapping and chirality sorting.2022 Chinese Laser Press
