【摘要】 根据双折射光纤中,参量放大和拉曼效应共同作用下的耦合波方程,在考虑高阶色散情况下,当输入泵浦波偏振方向同双折射轴成45°时,通过引入拉曼增益的洛伦兹模型,研究了双折射光纤中,参量放大和拉曼效应共同作用下的增益谱随相关参量的变化关系。结果表明,在反常色散区和正常色散区,在不同的输入参量(输入功率、群速度失配等)条件下,高阶色散的影响对参量放大和拉曼效应共同相互作用下的增益谱有重要影响;斯托克斯波与反斯托克斯波增益特性较光子晶体光纤表现出明显的不同。更多还原

【Abstract】 The coherently coupled nonlinear Schr dinger(NLS) equation in which Parametric Amplification and Raman scattering together acting in birefringence fiber has been utilized.Under think of Higher-order dispersive,The gain spectrums have been studied under Raman scattering and parametric amplification together acting when the pump wave polarization is oriented at 45°between the axes by quoting Lorentzian model of Raman gain spectra in high birefringence fiber.The result shows that the gain spectrums in which Raman scattering and parametric amplification together acting is influenced by Higher-order dispersive under different input parameters(input power,the group velocity mismatch) in the anomalous(or normal) dispersion regime.The gain spectrum of stokes and anti-stokes is different with photonic crystal fiber.更多还原
