色散渐减光纤中超连续谱产生的特性研究
Study on Super-Continuous Spectrum Generation in Dispersion-Decreasing Fiber
摘要
我们的研究结果表明,光纤的色散特征对光脉冲的传输和超连续谱的产生均有重要影响.由于色散渐减光纤的色散斜率不为零,因此脉冲在光纤中传输时产生不对称的情形,并最终产生不对称的光纤超连续谱.色散渐减光纤的色散斜率越小,越有利于脉冲和超连续谱的对称性,也越有利于超连续谱的展宽.
Abstract
Our research indicated that the dispersion characteristic of the fiber has much effect on pulse evolution and SC spectrum generation. While the pulse propagates in the fiber, it becomes asymmetrical and the asymmetrical SC spectrum is resulted eventually because the dispersion slope of the dispersion-decreasing fiber is not zero. The smaller the dispersion slope, the more asymmetrical the pulse and the SC spectrum are. It is more suitable for broaden SC spectrum generation when the dispersion slope is smaller.
