Influence of the third order dispersion on time delay difference in high birefringent optical fibers
摘要
依据强双折射光纤中两垂直偏振分量所满足的非线性耦合模方程
研究了三阶色散对偏振分量间的时延差的影响 .结果表明
当二阶色散、三阶色散同时存在时
三阶色散可以减小时延差 ;当只有三阶色散时
除了产生较大时延差外
还会在两个偏振脉冲的前后沿产生较大的色散波
Abstract
The influence of the third order dispersion on the time delay difference in high birefringent optical fibers is studied through nonlinear coupling mode equations. It is shown that when the effects of the second order dispersion and the third order dispersion exists simultaneously
the third order dispersion can decrease the time delay difference. When the third order dispersion effect exists
the more time delay difference is produced and the dispersion waves are produced at both the front and back edge of the pulse.
