%X The effect of cross phase modulation (XPM) on pulse propagation and supercontinuum (SC) spectrum generation in a dispersion flattened and decreasing fiber is researched. The results indicated that XPM could enhance the SC spectrum generation and increase the generation efficiency. Under certain conditions, in spite of their different modal indices the two polarized components of the pulse can trap one anther and move at a common group velocity due to XPM, the phenomenon referred as self trapping occur.
