Real-time optical interconnection using gratings applied by simple genetic algorithm

A pixelated binary phase grating to generate 5x5 spots is designed using a simple genetic algorithm (sGA) composed of selection, crossover and mutation operators, and it can be applied for optical interconnections. GA is a random search algorithm based on the mechanism of natural selection and natural genetics; it is a robust and efficient scheme. sGA for a phase change of each pixelated grating is applied to minimize a difference between the Fourier transform results and the desired pattern.
