Paper Abstract

We propose a novel algorithm for designing diffractive optical elements, which uses the concept of adaptive simulated annealing and ensemble simulated annealing. We iteratively rescale the temperature in the end of each quenching process, according to the ensemble statistics, to bring the system back from a frozen state to thermodynamical equilibrium for avoiding the local minimum. The process is used to design binary phase irregular spot array generators. The diffractive element has trapezoidal apertures of varying heights that are adapted to the e-beam plotting and provide a large number of degrees of freedom.
