We present a new computational scheme to design supercontinuum spectra "ÃÂ la carte" by means of Genetic Algorithms. Due to the potentially large amount of computations required by this strategy, the deployment of these heuristic algorithms is performed using distributed computing in the form of a Grid platform. The optimization procedure is automated within the Grid platform and permits escalation to large computational Grids. Some examples of designed supercontinua are given and potential applications for the design of future photonic devices are briefly described.© (2010) COPYRIGHT SPIE--The International Society for Optical Engineering.
