ABSTRACT:
A diffraction grating including a substrate, and a grating member formed on the substrate, the grating member having a stepped structure including steps, the number of which corresponds to an odd number greater than or equal to three to provide an odd phase structure. The heights of the steps of the grating member are determined such that the light beams diffracted by their corresponding steps substantially have a phase difference of π with reference to a diffracted light beam of a reference wavelength.
