The results of numerical modelling of the supercontinuum generation in microstructure fibers excited by femtosecond multi-soliton pulses are presented. Pulse dynamics is modelled using the extended Schrodinger equation, in which the dispersion and nonlinear coefficient for given fiber are calculated by plane wave method. It is more easy to achieve the phase-matching conditions for the dispersive wave generation in the fibers with periodical modulated diameter. It is shown that the periodical modulation of fiber diameter allows to control the spectrum of multi-soliton pulses that leads to spectral broadening and disappearance of the gap between spectra of soliton and dispersive wave.
