摘要
运用偏振度(DOP)椭球法从实验的有限样点数据中获得了差分群时延和偏振主态方向,这为前馈补偿实验提供了最关键的技术因素.在实验中获得了偏振主态方向和DGD,而且当DGD较小时,从实验所获得的DGD值与理论模拟的变化趋势基本一致.结果表明当DGD较小时,可以用偏振度椭球法从实验上得到正确的DGD和偏振主态方向.
Abstract
By using the degrees of polarization (DOP) ellipsoid method,the values of differential group delay (DGD) and the direction of the principal sterte of polarization (PSP) were obtained from limited sampling data in the experiment,which provided the most key factors of the feed-forward compensation scheme. Moreover,the values of DGD obtained from the experiment were accordant with that of the theoretical values when the DGDs were less than 30 ps. Results indicated that DGD and the orientation of PSP could be obtained by using the DOP ellipsoid method in the experiments.
