Abstract
Permutation elements can reorder and change the spacing of a set of input channels at an output plane. A two-dimensional implementation of these elements is currently of interest as a component in switching networks. The realization of such elements is theoretically and experimentally analyzed. Each grating is individually recorded in a rotated position in respect to the others. In this way arbitrary 2-D interconnections are achieved at the cost of higher design requirements. To produce these elements with high diffraction efficiency at reconstruction with the light of mixed polarization increases the recording complexity. The Fresnel reflection coefficients add further to the difficulty of the theoretical analysis. Experimental and theoretical results are compared. Two demonstration components were implemented.
