py-fmas swMATH ID: 38301 Software Authors: O. Melchert, A. Demircan Description: py-fmas is a Python package for the accurate numerical simulation of the z-propagation dynamics of ultrashort optical pulses in single mode nonlinear waveguides. The simulation approach is based on propagation models for the analytic signal of the optical field. The software implements various models of the Raman response and allows to calculate spectrograms, detailing the time-frequency composition of the analytic signal. Additionally, a convenience class for analyzing propagation constants is provided.
