摘要
介绍用扫描法研制成功的长 13 5cm、带宽 0 44 7nm、反射谱平坦的切趾啁啾光纤光栅 ,功率波动小于1dB ,用色散分析仪测试得到时延曲线上的纹波系数小于 2 0 ps,用该光纤光栅对 2 0 0km的G 6 5 2光纤色散补偿 ,补偿量大于 98% (原始脉冲宽度为 36 78ps,色散补偿后的脉冲宽度为 37 2 3ps)。
An apodization chirp optical fiber grating (OFG) is fabricated by scanning method. This OFG is 13.5 cm long with 0.447 nm bandwidth its reflectivity is flatness with ripple coefficient less than 1 dB, while its ripple coefficient of time delay is less than 20 ps. The dispersion of 200 km G. 652 optical fiber is compensated by the grating, and more than 98% dispersion is compensated (the original pulse width is 36.78 ps, after compensation the pulse width is 37.23 ps).
