摘    要:利用有机玻璃块和螺旋测微器组成的简支梁系统调谐线性啁啾光纤光栅,将中心波长为1548.6nm、3dB带宽为0.43nm、长为25mm的均匀Bragg光纤光栅按一定角度牢牢的固定在一块长为90mm,宽为10mm,高为5.2mm的有机玻璃块中,再用螺旋测微仪在有机玻璃的中心位置向下施加压力,使简支梁及其中的光纤光栅变形,成为可调谐的啁啾光纤光栅。实验结果表明啁啾光纤光栅反射谱宽与简支梁弯曲量成线性关系,当简支梁最大弯曲量为1.2mm时光纤光栅反射谱展宽了4.02nm,而反射中心波长基本不变,该实验装置可以用于光控相控阵雷达天线的实时延迟线和光纤色散补偿。

关 键 词:简支梁  调谐  啁啾光纤光栅  实时延迟线  色散补偿

Abstract:A simply-supported beam system is constructed to tune linearly chirped fiber grating(CFG) by making use of a plexiglass block and a screw micrometer.A uniform fiber Bragg grating(FBG) is firmly and angularly pasted in the plexiglass block with length of 90mm,width of 8 mm,and height of 5.2 mm.The center wavelength,FWHM,and length of the FBG are 1548.6nm,0.43 nm,and 25mm,respectively.To obtain a tunable CFG,a pressure is exerted at the middle point of the simply-supported beam to make the simply-supported be...
Keywords:simply-supported beam  tuning  chirped fiber grating(CFG)  true-time delay  dispersion compensation
