摘要
The properties of the self-similar parabolic pulses interaction in a dispersion-decreasing optical fiber with normal group-velocity dispersion are firstly investigated in our paper. We find that two parabolic pulses separated by a time-delay create oscillation with a sinusoidal fit at the beginning of their overlap, and then further evolve into a train of asymptotic dark solitons. Additionally, outside the overlap regime, the evolution is equal to a single pulse' propagating behavior. The chirp after interaction in the parabolic pulses still allows for efficient and high-quality pulse compression. (c) 2008 Elsevier GmbH. All rights reserved.
