Study on chirps induced by the high-order nonlinear effects in the negative refractive media
Based on the generalized nonlinear equation of negative refractive media, the self-phase modulation chirp, self-steepening chirp, fake-quintic nonlinearity chirp, second-order nonlinear dispersion chirp and total chirps induced by all nonlinear effects are simulated by using the split-step Fourier method. The results show that the center of the pulse can shift both the leading edge and the trailing edge because the parameter of self-steepening can be negative and positive. In normal dispersion area, the fake-quintic nonlinearity leads to the broadening of pulse if the parameter of fake- quintic nonlinearity is negative, the second-order nonlinear dispersion leads to the broadening of pulse if the parameter of second-order nonlinear dispersion is positive and the compression of pulse if the parameter is negative.
