| 摘 要： | 研究了色散缓变光纤中超短光脉冲的Raman孤子自频移现象。利用绝热扰动方法得到了一个关于Raman孤子自频移的普遍表达式。结果表明：光纤色散缓变率存在一个能抑制超短光脉冲的Raman孤子自频移的阈值，只有当色散缓变率小于这个阈值时，色散缓变光纤才能有效抑制超短光脉冲的Raman孤子自频移。

| Abstract: | Raman soliton self-frequency shift (SSFS) of ultrashort pulses propagating in a dispersion-decreasing fiber (DDF) is studied in this paper. A general expression for SSFS is obtained using the adiabatic perturbation approach. It is shown that there exists a threshold of the rate of the fiber dispersion decrease for the suppression of SSFS of solitons propagating in DDFs, only when the rate of the fiber dispersion decrease is less than the threshold can SSFS be suppressed in the DDF. |
