Abstract:

Based on the analysis of the characteristic of ultrashort optical soliton, TOD and Raman scattering influences were taken into account. It found out the relationships between and , Z, by using the Numerical simulation method, Analysis method and Fitting method. It improves the self-frequency shifting calculating formula which considered Raman scattering influence only. It also studied the volume of the pulse delay caused by the self-frequency shifting. The result indicates that the amount frequency shifting caused by TOD is: , the amount pulse delay is: ,the pulse delay caused by TOD is: . This result is very important for the high-speed optical switch.

Key words: nonlinear optical, TOD, finite element difference method, self-frequency shifting
