摘要
主要从平均色散、插入损耗、群时延波动(group delay ripple)的幅度和周期随切趾深度的变化等方面,分析了切趾线性啁啾光纤光栅的切趾深度对其特性的影响。并以补偿100km、光纤色散系数Df为17ps/nm·km(1550nm处)的标准单模光纤的色散为例,定量地分析了切趾深度对光纤光栅特性的影响,获得了切趾深度的最优化值。
The effect of the apodisation sharpness on apodisated linely chirped fiber gratings was analyzed from the behavior of mean dispersion, insertion losses, the amplitude and the period of mean group delay. A 10 Gbit/s simulation system was designed with 100 km standard single-mode optical fiber （Dr =17 ps/nm-km at 1550 nm）, whose chromatic dispersion was compensated by apodisated linearly chirped fiber gratings. The simulation shows the behavior of stronger dependence of fiber gratings on the apodisation sharpness and the value of optimum apodisation sharpness.
