Abstract

In modern architectures of digital optics and material processing the splitting of an incoming light beam into an array of prescribed intensity light spots is of fundamental concern. The high efficiencies and the flexibility of the optical function encourage researchers in the design of diffractive phase gratings. The design problem is to find a phase transmittance or reflectance whose diffraction pattern contains an area of prescribed intensity. We call the diffraction pattern in this area the desired signal wave.
