Abstract: (5272 Views)
A model based on the complex Ginzburg-Landau equation governing the evolution of an optical pulse in a dissipative media is considered. This equation has complex dispersion and nonlinearity coefficients and an extra first-order spatial derivative term multiplied by imaginary part of group velocity. In order to provide more insight into the physical meaning of these coefficients, the effect of variation of coefficients on propagation of a Gaussian pulse is investigated. The separate effects of imaginary parts of group velocity, dispersion and nonlinearity coefficients on dynamics of Gaussian pulse are inspected in temporal as well as in Fourier (spectra) space
