1) Raman soliton self-frequency shift
Raman自频移
2) Raman soliton self frequency shift
Raman孤子自频移
3) self-frequency shift
自频移
1.
The numerical results show that the self-frequency shift and self-steepening make the pulse drift backward nonlinearly,and the drift of the former pulse smaller than that of the latter.
数值结果表明:自频移和自陡峭都使脉冲向后沿呈现非线性的偏移,前一个脉冲的偏移量很小,基本上是呈线性偏移,后一个脉冲随传输距离的增加,偏移量逐渐的增大,呈非线性偏移。

The interaction between femstosecond optical pulses under Raman self-frequency shift effect and the suppression of it are studied by using numerical simulation.
数值模拟了Raman自频移效应下fs光脉冲间的相互作用及其抑制,结果表明:Raman效应的存在使得fs脉冲的相互作用与常规的ps脉冲间的相互作用不同,在初始阶段孤子相互吸引,而后一直处于排斥状态,脉冲间距随传输距离增加而增大,脉冲在传输过程中发生漂移,孤子产生能量交换,传输距离显著减小,严重影响了通信质量;同步幅度调制、非线性增益与滤波器相结合可有效抑制Raman效应下fs光脉冲间的相互作用。

The characteristic and principle of two-order soliton′s transmission under the effects of self-steepening effect and self-frequency shift effect are deeply studied separately.
对二阶孤子在自陡峭(Self Steepening,简称SS)和自频移(Self FreguencyShift,简称SFS)两种高阶非线性效应影响下的传输特征及原理分别进行了研究,讨论了二阶孤子衰变产生的两个基孤子的峰值强度比与自陡峭参量、自频移参量之间的关系。
4) spikes in raman spectrum
Raman频谱尖峰
1.
The results of theoretical calculation showed that the spikes in raman spectrum of V 2:a→sR(0,0) would appear,when the operating NH 3 gas pressure was higher than a certain critical value or pumping power density was lower t.
理论计算结果表明 ,对于 a→ s R(0 ,0 )跃迁 ,当工作气压比临界值 Pc高或泵功率密度比临界值 Ipoc低时 ,将出现 Raman频谱尖峰 ;对于 a→ s Q(5,4)跃迁 ,不出现频谱尖峰。
5) Soliton self-frequency shift
孤子自频移
1.
The non-linear effect of soliton self-frequency shift(SSFS) in photonic crystal fiber is analyzed.
理论分析了光子晶体光纤中孤子自频移(Soliton Self-Frequency Shift,SSFS)这一光纤的非线性效应,研究了利用SSFS实现波长变换的薛定谔方程求解问题,讨论了输入功率、PCF的长度、非线性系数等参数对波长变换范围及转换效率的影响,指出输入功率与PCF的长度相对于波长变换的输出中心波长从几纳米到几十纳米基本呈线性变化,当使用较长的PCF时,光纤中的高阶孤子和孤子分裂效应将限制波长变换的效率。
