In the design of comb‐like dispersion‐profiled fiber (CDPF) for pulse compression, the length of the dispersion shift fiber (DSF) is determined by the nonlinear phase shift of each segment. To achieve a higher compression factor, it is necessary to increase the phase shift experienced by the pulse in each segment. However, a too large phase shift generally results in severe pulse distortion or breakup and the shedding of a large proportion of the pulse energy to a dispersive background level. Pulse‐compression experiments are made with three different CDPFs of different nonlinear phase shifts and a high‐quality compression effect is achieved. © 2003 Wiley Periodicals, Inc.
