A vectorial vortex optical field polarization conversion device and a construction method and system thereof

Abstract

The application discloses a vector vortex light field polarization conversion device and a construction method and system thereof, relates to the field of polarization conversion applications, and comprises a substrate layer and a super atom unit layer; the super atom unit layer is arranged on the substrate layer; the super atom unit layer comprises a plurality of super atom ring bands; the super atom ring band comprises a plurality of super atom units; the intervals between the super atom units are equal; the super atom units are consistent with the attributes of a 1 / 4 wave plate or a general wave plate; and the super atom unit layer is used for converting incident circularly polarized light into radial polarization light and angular polarization light carrying first-order orbital angular momentum. The vector vortex polarization conversion device constructed by using the super atom unit not only solves the problem of low transmittance of a traditional vector vortex polarization conversion device, but also simplifies the construction process of the vector vortex light field polarization conversion device.
