Résumé
A new global optimisation algorithm is presented and applied to the design of high-channel-count multichannel filters based on sampled Fibre Bragg Gratings (FBGs). We focus on the realisation 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 (GA) and by the classical Sinc method.
