Broadband blazing with artificial dielectrics
Résumé
The efficiency of conventional diffractive optical elements with échelette-type profiles drops rapidly as the illumination wavelength departs from the blaze wavelength. We use high dispersion of artificial materials to synthesize diffractive optical elements that are blazed over a broad spectral range ( 1 octave) or for two different wavelengths.
