Abstract

The strength of volume holographic grating being uniform throughout material depth, the efficiency of such a grating as a function of angle or wavelength has several side-maxima with magnitude comparable to that of main maximum. The side-maxima can be the origin of noises and lack of selectivity of holographic optical elements and devices such as demultiplexers, filters, etc.
