【 摘 要 】

When ultrashort pulses with large enough power are launched into highly nonlinear fibers, soliton fission gives origin to multiple fundamental solitons of different widths and peak powers. Two soliton related effects become then particularly important in the context of supercontinuum generation: the soliton self-frequency shift and the emission of dispersive radiation in the normal dispersion region. The dispersive characteristics of the optical fiber assume play a key role in these circumstances.
