光纤中五阶非线性极化效应对黑脉冲传输的影响

Effect of the Fifth-order Nonlinearity on the Dark Pulse Propagation in Fibers

考虑到光纤折射率的五阶非线性极化效应,本文对不同初始条件下,光纤中黑脉冲的传输进行了数值模拟分析。结果表明,高阶非线性极化效应对黑脉冲的分裂具有推迟作用。

Taking into account the fifth-order nonlinearity in the refractive index of the fiber, the dark pulse propagation in fibers is simulated numerically for the varying initial conditions. It is shown that higher-order nonlinear effect can delay the dark pulse breakup.
