MiSiM:Microstructured Fibers' Simulator

In this work we present MISIM: a free and open software tool for the simulation of microstructured fibers, that can be used for the calculation of their dispersion profiles, for its design and posterior manufacturing. The software is based on the numerical model of Saitoh and Koshiba, and it is able to simulate chromatic dispersion, effective index and group index for a given spectral range. MISIM generates output text files as well as line charts of the simulated parameters. As far as we known, it is the only open and free software with a GUI that can visualize its output directly. For the validation of the tool, results from MISIM were compared with those reported in the literature using different methods to calculate their profiles, obtaining, for example effective indexes within one standard deviation of those reported. Even smaller errors (2.61%) were obtained for the chromatic dispersion using our proposed tool.
