Abstract
A theoretical approach to the design of high efficiency multilevel thin film phase-only gratings is reported. The discussion shows that a film optimum thickness and refraction index must be set in designing DOE components with maximum diffraction efficiency. Experimental results related to the grating''s chromatic behavior vs. the thin film parameters are also presented. These results show good agreement with the expected values foreseen by theory.
