摘要:
该文从理论上研究了线性啁啾变迹光纤光栅及均匀光纤光栅的反射谱。经分析发现 ,高斯分布的耦合系数具有平滑反射谱、消除旁瓣的作用 ,啁啾系数的增大使得光栅的反射谱明显变宽、最大反射率降低 ,利用这个规律 ,可选择恰当的参量 ,制作出符合工程要求的光纤光栅 ;同时也发现均匀“弱”光纤光栅的反射谱具有sa (x)函数的分布特性。在此基础上提出用“弱”光纤光栅做匹配光滤波器的设想
Abstract:
This paper theoret ically studied on the reflect ion spect rum of linear chirped Gauss apodized OFBG ( opt ical fiber Bragg grat ing ) and of uniform OFBG, found that the apodized function can smooth the ref lect ion spectrum, increasing the chirp coefficient can broader the ref lect ion bandw idth, but at the same t ime reduced the maximum ref lect ivity . Using this rule guide us to fabricate the suitable OFBG. In addit ion, under w eak condit ions( K 0 < 1 ) , the amplitude reflection of a uniform OFBG is analyzed. The spect rum has a characteristic of sa( x ) shape. Base on this, the paper proposed an assume to use w eak OFBG as matched opt ical filter.
