Four-wave interference and perfect blaze
Four-wave interference and perfect blaze is a scholarly work, published in 2012 in ''Optics Letters''. The main subjects of the publication include optics, anti-reflective coating, physics, wavelength, diffraction, Blazed grating, silicon photonics, Electromagnetically induced grating, cross section, diffraction grating, diffraction efficiency, interference, dimensional metrology, and grating. The recently calculated high diffraction efficiencies for TE- and TM-polarized light (perfect blaze) for echelette gratings are explained by four-wave interference, which is formed as a double periodical pattern in the cross section of the grating plane.
