Abstract
Diffractive optical elements (DOEs) are designed by the simulated annealing method for simultaneously implementing color separation and light focusing (CSLF) functions. Through changing the maximum permitted phase, the quantization level number, the input pixel number or the target focusing region width, various CSLF DOEs are optimally designed. Optical performances of the designed DOEs are calculated by the Fresnel diffraction integral method. Simulation results reveal that the designed DOEs not only successfully realize the expected CSLF functions, but also exhibit an excellent performance of high focusing efficiency or high signal to noise ratio under specific parameter circumstances. It is expected that the designed DOEs should have practical applications in solar cell systems or optical interconnection systems.
