Abstract
Dammann gratings are binary phase gratings that are used to produce a one- or two-dimensional array of equal-intensity light spots. Recently, Dammann gratings have become of interest for their ability to provide the optical power supply to an array of optical logic devices from a single laser source. We present here a feasibility study of Dammann gratings, in which we consider several parameters that are important for the computation and fabrication of the gratings. As a result of this investigation we conclude that Dammann gratings are useful for array sizes up to about 40 x 40 spots. Above that size, problems with the computation of the gratings and with the resolution become dominant.
