We suggest that a three-level cascade medium be used to achieve the switching from normal dispersion to anomalous dispersion.

建议利用三能级级联型介质实现从正常色散到反常色散的变换。

In the anomalous dispersion regime of fiber gratings, optical pulse can come into being bright solitons by a careful control of SPM、XPM and GVD, in the normal dispersion regime of fiber gratings can allowed transmission of dark solitons.

在光纤光栅中,当入射频率位于布拉格频率附近时,结构色散在系统中占主导地位,材料色散和波导色散等因素可忽略不计,在光纤光栅的反常色散区,由结构色散造成的群速度色散(GVD)效应和由自相位调制(SPM)、交叉相位调制引起的非线性效应的相互作用,可导致光纤光栅中亮孤子的形成;而在光纤光栅的正常色散区也能够维持暗孤子传输。

Taken into account second order dispersion and self-phase modulation in the normal-dispersion region of single-mode fibers by means of Fourier-transform algorithm,the results show that negative initial chirps can be compressed owing to normal GVD,we also show that SPM degrades pules compression.
