摘要
为了研究高阶色散和高阶非线性效应对其在普通光纤上传输的影响,用数值模拟的方法研究了三阶色散、自陡效应和脉冲内拉曼散射效应对准光孤子传输的影响。结果表明准光孤子在实际的普通光纤中传输时,三阶色散、自陡效应和脉冲内拉曼散射效应中,冲内拉曼效应对其传输产生的影响比较大,致使准光孤子在普通光纤上传输时脉冲不断展宽,脉冲峰值功率降低,不能长距离保持脉冲形状不变。
Considering the influence of high-order dispersion and high-order nonlinearity on quasi-soliton transmission, the effects of third-order dispersion, self-steepening and ISRS are investigated by numerical simulation. The result indicates that among these three effects, the influence of the ISRS effect on quasi-soliton transmission in the actual fiber is primary. Under the influences of these effects, the width of quasi-soliton broadens, the peak value of the pulse descends and the shape of the pulse cannot keep as the original shape.
