Abstract :
Microstructured fibers with periodically modulated diameter are proposed for controlling supercontinuum generation. We report the results of numerical study of spectral broadening of low-order femtosecond solitons. It is shown that periodical modulation of phase-matching conditions leads to spectrum broadening and disappearing of spectral gap between spectra of soliton and dispersive wave. The structure of output spectrum depends on the period of the modulation of the diameter of microstructured fiber
