Effects of Higher-order Dispersion on Time Delay in Femtosecond Pulse Generated from a Nonlinear Optical Loop Mirror Constructed from Dispersion Decreasing Fiber
The time delay(TD) of femtosecond pulses is studied for the first time, which generated from the nonlinear optical loop mirror composed of dispersion decreasing fiber(DDF-NOLM). The results show that the higher-order dispersion and high order nonlinearities such as Raman frequency shift play a key role in producing TD, and that the time delay can be suppressed by the third-order dispersion(TOD) in DDF-NOLM. The mechanism of the time delay suppression is also discussed in detail.
