得到了飞秒孤子在色散缓变光纤(FSDD)中的绝热压缩，发现了孤子在FSDD中的脉宽稳定效应，提出了描述飞秒脉冲在FSDD中传输的理论模型。该模型考虑了光纤中的高阶非线性和色散效应。我们给出了一个广义非线性薛定谔方程的数值模拟和绝热孤子近似理论。理论和实验之间有很好的定量一致性。描述了FSDD中孤子脉宽稳定效应是三阶色散效应和拉曼自散射效应共同作用的结果。我们还展示了在1.6FSDD中通过孤子压缩获得脉冲宽度小于15-μ的高质量脉冲的可能性。
We obtain the adiabatic compression of femtosecond solitons in fibers with slowly decreasing dispersion (FSDD’s) and discover the effect of soliton pulse-width stabilization in FSDD’s. A theoretical model for the description of femtosecond-pulse propagation in FSDD’s is presented. The model takes into account higher-order nonlinear and dispersive effects in fibers. We present numerical simulations of a generalized nonlinear Schrodinger equation and the adiabatic soliton approximation theory as well. Good quantitative agreement between the theory and the experiments is seen. The effect of soliton pulse-width stabilization in FSDD’s is described as a result of the combined action of the third-order dispersion and Raman self-scattering effects. We also show the possibility of obtaining high-quality pulses with less than a 15-fs pulse width in the 1.6-μm spectral region by soliton compression in FSDD’s.
