The limiting factors in short pulse generation by gain switching of semiconductor lasers are analyzed using an approach parallel to conventional Q switching analysis. The dependence of the gain-switched pulse width and pulse energy on various input parameters such as drive current amplitude, bias current, and spontaneous emission factor, etc., can be predicted in a simple manner.

    We have considered soliton pulse compression in a dispersion decreasing ideal elliptical birefringent fiber with phase modulation.
