Abstract

This paper deals with phase gratings working in the paraxial domain. The profile of the optimum-efficiency beam multiplier with an arbitrary number of output diffraction orders is derived in an analytic form by exploiting methods from the calculus of variation. The output beams may be equiintense or with arbitrary distribution of power. Numerical examples are given for different values of the number of output beams.
