The Numerical fitting on ultrashort optical soliton self-frequency shifting

Based on the analysis of the characteristic of ultrashort optical soliton, third-order dispersion (TOD ) and Raman scattering influences were taken into account. The quantitative relationship between the self-frequency shifting with distance, pulse width and TOD are found out using the Numerical simulation and fitting method. The size of the pulse time delay is also studied caused by the self-frequency shifting. The results are obtained the quantitative relationships between the self-frequency shifting and pulse time delay with distance, pulse width and TOD, which are very important for the high-speed optical switch.
