Abstract:
A method of making an optical member including high refractive index layers and low refractive index layers, which are each relatively thin as compared with an optical length, and disposed alternately in the lateral direction with respect to an optical axis. Each width of the high refractive index layers and the low refractive index layers is equal to or smaller than the wavelength order of incident light.
