Advances in Polarization Detectors Based on Metasurfaces
Polarization detection technology is a vital optical sensing method characterized by its strong anti-interference capabilities and its effectiveness in enhancing detection range.It plays a significant role in various fields,including optical remote sensing,environmental monitoring,bio-medicine,and underwater imaging.However,traditional polarization detection systems encounter challenges,such as bulky size and complex optical paths,which create substantial obstacles for miniaturization and integration.Metasurfaces,comprised of two-dimensional periodic arrays of artificially subwavelength elements,enable precise manipulation of optical fields according to the polarization states of incident light.This capa-bility effectively reduces the size of polarization detection systems while enhancing device integration,offering innovative solutions for miniaturized polarization detection.This review analyzes the optical field manipulation mechanisms related to polarization detection and summarizes photon and photothermal polarization detectors based on metasurfaces.Additionally,it discusses existing challenges and future trends,aiming to provide valuable insights for further research in this field.
