Abstract

Closed form analytical solutions of diffraction efficiency for transmission surface relief gratings in the resonance domain are presented. These are obtained by modeling the surface relief gratings with equivalent graded index gratings having Bragg properties, so as to allow for an optimum choice of grating parameters that would lead to high diffraction efficiencies. The calculated and experimental results reveal that the diffraction efficiency can be greater than 85% with optimized grating parameters within their certain strict limits.
