| 摘 要： | 从原理上证明了一种基于非线性啁啾光纤光栅以及光纤光栅的温度特性的色散可调谐方案.实验证明在25.5℃的温度变化范围内,光纤光栅对1550.43nm波长的色散补偿量从759.1ps/nm上升到1659.9ps/nm,色散调谐范围达到900ps/nm,这个方案具有对补偿波长和特定补偿波长所需要的色散补偿量同时进行调谐的特点.

| Abstract: | Based on nonlinear chirped FBG whose dispersion will change with the wavelength and its temperature character,one scheme which can realize the tunable dispersion compensation has been demonstrated.By properly tuning nonlinear chirped FBG’s temperature from 26.4℃ to 52.3℃,nonlinear chirped FBG’s dispersion as to certain wavelength (1550.43nm) changes from 759.1ps/nm to 1659.9ps/nm,i.e.900ps/nm dispersion compensation has been achieved in the experiment.Furthermore,this scheme has the characteristic that not only the dispersion compersation of certain wavelength but also the compersation wavelength can be tuned at the same time. |
