Paper Abstract

Study on the combination of different optimal algorithms to improve the performance of the algorithm is crucial to design optical multiplayer. A method based on GA (Genetic Algorithm) and NLSM (nonlinear least square method) is presented in this paper. GA is used to optimize the refractive index of the optical multilayer to get the original structure parameters. Then the NLSM is used to optimize the thickness of the optical multilayer based on the previous result. The algorithm model is explained in detail and the optimization design examples prove that the result is better. The results also indicate that the method is simple, effective and general for the optical multilayer design.
