Abstract
The analytical expression of the phase profile of the optimum diffractive b eam splitter with an arbitrary power ratio between the two output beams is derived. The phase function is obtained by an analytical optimization proce dure such that the diffraction efficiency of the resulting optical element is the highest for an actual device. Comparisons are presented with the eff iciency of a diffractive beam splitter specified by a sawtooth phase functi on and with the pertinent theoretical upper bound for this type of element.
