Computer generated optical fan-out element

Abstract A multi-facet holographic technique for optical beam fan-out is presented. The total power to the 1/e 2 point of an elliptical gaussian beam is distributed within a two-dimensional array of square outputs by use of an analytically formulated multi-facet holographic element. Results of a computer generated holographic optical element to perform optical fan-out to a 5 by 5 array of squares is presented.
