| 摘 要： | By considering higher-order effects, the properties of self-similar parabolic pulses propagating in the microstructured fibre amplifier with a normal group-velocity dispersion have been investigated. The numerical results indicate that the higher-order effects can badly distort self-similar parabolic pulse shape and optical spectrum, and at the same time the peak shift and oscillation appear, while the pulse still reveals highly linear chirp but grows into asymmetry. The influence of different higher-order effects on self-similar parabolic pulse propagation has been analysed. It shows that the self-steepening plays a more important role. We can manipulate the geometrical parameters of the microstructured fibre amplifier to gain a suitable dispersion and nonlinearity coefficient which will keep high-quality self-similar parabolic pulse propagation. These results are significant for the further study of self-similar parabolic pulse propagation.

| Abstract: | By considering higher-order effects, the properties of self-similar
parabolic pulses propagating in the microstructured fibre amplifier
with a normal group-velocity dispersion have been investigated. The
numerical results indicate that the higher-order effects can badly
distort self-similar parabolic pulse shape and optical spectrum, and
at the same time the peak shift and oscillation appear, while the
pulse still reveals highly linear chirp but grows into asymmetry. The
influence of different higher-order effects on self-similar parabolic
pulse propagation has been analysed. It shows that the
self-steepening plays a more important role. We can manipulate the
geometrical parameters of the microstructured fibre amplifier to gain
a suitable dispersion and nonlinearity coefficient which will keep
high-quality self-similar parabolic pulse propagation. These results
are significant for the further study of self-similar parabolic pulse
propagation. |
