LINEARLY POLARIZED LIGHT CONVERSION ELEMENT, MANUFACTURING METHOD AND LINEARLY POLARIZED LIGHT CONVERSION SYSTEM

摘要

Provided are a linearly polarized light conversion element, a manufacturing method and a linearly polarized light conversion system. The linearly polarized light conversion element comprises: a substrate (1) and a metasurface (2) provided on the substrate (1). The metasurface (2) comprises at least one light field modulation region (100), each light field modulation region (100) comprises at least one metasurface function unit (20), and the metasurface function unit (20) comprises an anisotropic sub-wavelength structure (201). In a light field modulation region (100), the direction of a long axis of each sub-wavelength structure (201) is identical.
