Abstract
A technology that allows improvement in the performance of an optical element a representative example of which is a polarizing element is provided. In a split wire element according to an embodiment of the invention, each of a plurality of split wires (SPW) has gaps formed in a y direction at a period Λ, and the period Λ is greater than or equal to a Rayleigh wavelength (λ/n). According to the thus configured split wire element of the embodiment of the invention, optical performance can be improved as compared with a wire-grid element formed of straight wires having no periodic structure in the y direction.
