Amplification of Frequency‐Modulated Similariton Pulses in Length‐Inhomogeneous Active Fibers

International Journal of Optics, Volume 2012, Issue 1, 2012., 2012
The possibility of an effective gain of the self‐similar frequency‐modulated (FM) wave packets is studied in the length‐inhomogeneous active fibers. The dynamics of parabolic pulses with the constant chirp has been considered. The optimal profile for the change of the group‐velocity dispersion corresponding to the optimal similariton pulse ...
