Abstract

This paper is a study on the generation of high speed ultra-short pulse series by using a 10 GHz DFB gain-switch semiconductor laser. An analysis concerning the compression property of an optic pulse in dispersion decreasing fiber is presented through solving of the nonlinear Schrodinger equation by means of a numerical method. The output optical pulse of a LiNO₃ electro-optical modulator that has a frequency of twice that of the electrical driving signal can be compressed in dispersion decreasing fiber. Furthermore, the best way of substituting the dispersion decreasing fiber with comb-like dispersion fiber is now available
