Spectral broadening and generation of new frequency components are some of the inherent features of the nonlinear optics. The specific process in which an incident pulse with a narrow spectral width undergoes extreme broadening, generating an output with extensive width, is known as Supercontinuum Generation (SCG). SCG has many applications in spectroscopy, pulse compression, tunable ultrafast femtosecond laser sources design, optical coherence tomography and optical frequency metrology.
Supercontinuum process has a complicated mechanism whose thorough analysis is difficult. In accordance with this fact, many investigators have done comprehensive investigation on different mechanisms in SCG. Important mechanisms in supercontinuum process are the self-phase modulation (SPM), the cross phase modulation (XPM), the four wave mixing (FWM), the stimulated Raman scattering (SRS), the self-steepening (SS) and the soliton fission.
When a photonic fiber with a wide wavelength range of anomalous group velocity dispersion (GVD) is used to generate a supercontinuum, it is possible to create a soliton. We can produce fundamental and high-order solitons in the fiber by suitable choice of parameters.
