RT Journal Article T1 Semi-Deterministic vs. Genetic Algorithms for Global Optimization of Multichannel Optical Filters A1 Ivorra, Benjamin A1 Mohammadi, Bijan A1 Redont, Patrick A1 Dumas, Laurent A1 Durand, Olivier AB A new global optimization algorithm is presented and applied to the design of high-channel-count multichannel filters based on sampled Fiber Bragg Gratings. We focus on the realization of particular designs corresponding to multichannel filters that consist of 16 and 38 totally reflective identical channels spaced 100 GHz. The results are compared with those obtained by a hybrid genetic algorithm and by the classical sinc method.
