Abstract

Propagation characteristics of the femto-second chirped soliton pulse in dispersion-flatted fiber with linear dispersion profile (DFF-LDP) are numerically investigated by using the split-step Fourier method (SSFM), and variations of its characteristics affected by high-order dispersion (β2~β6), Raman effect, fiber loss and linear chirp parameter C are studied. A new type of DFF-LDP with negative dispersion slope is presented. The pulse broadens with the increase of propagation distance mainly because of fiber loss and third order dispersion (TOD). The effect of the positive chirp on pulse broadening is greater than that of the negative chirp. The time-delay induced by TOD and Raman effect appears, and decreases with increase of the chirp |C|. The main body of the pulse spectrum shifts to the long-wavelength region, an obvious separated spectrum appears in the short-wavelength region. The separated spectrum for the chirped case is more obvious than that for the unchirped case.
