Abstract: Using a FM Gaussian pulse travelling in a two-mode periodic optical fibre as an example, it is shown that dispersion parameters caused by the complexity of the refractive index substantially affect the pulse dynamics. In particular, the imaginary part of the effective dispersion enables one to compress a pulse in an amplifying medium without its initial frequency modulation.
