Abstract

We demonstrate, through simulation, an optimization method based on genetic algorithms applied to propagation of ultrashort (femtosecond) pulses in single-mode optical fibers. The algorithm employs a feedback loop that acts on a pulse shaper (spectral amplitude filter) in response to a fitness function based on the output pulse. The system evolves toward an optimum filter configuration that, in contrast to unfiltered pulse propagation, when it is applied to shape the input pulse permits successful transmission of the pulse without loss of intensity or pulse width.
