New systems are being developed around innovative diffractive optical components. Applications in optical interconnects, signal switching and interferometry have created a need for two-dimensional optical fanout gratings as well as complex Diffractive Optical Elements (DOE). The increasingly complex components being designed for such optical devices require specialized optimization algorithms to achieve desired performance. In this paper, we demonstrate the optimization of 1:K fanout gratings and symmetrical DOE's in a highly dimensional solution space using genetic algorithms (GA). Analytic results are presented for the optimization of an interconnect grating using different GA parameters to analyze the algorithm convergence. By means of these examples, we present design techniques for fanout gratings, radially symmetric DOE's, and polarization sensitive components. |
