    • A technique is described for reducing group delay ripple in a fiber dispersion compensation grating. The grating is mounted into a trimming setup that includes a trimming device and a scanning assembly for causing a region of the grating to be scanned along its length by the trimming device output. The grating is sensitive to the trimming device output, such that exposure to the trimming device output causes a change in the effective refractive index of the scanned region, the amount of change varying as a function of scanning velocity. A region of the grating to be trimmed is selected, and a scanning velocity profile is programmed into the scanning assembly that is calculated to modify the effective refractive index of the selected grating region along its length so as to smooth out group delay ripple in the selected grating region.
    • 描述了一种用于减少光纤色散补偿光栅中群组延迟纹波的技术。 光栅被安装到修剪装置中,该修剪装置包括修剪装置和扫描组件,用于通过修剪装置输出沿着其长度使光栅的区域被扫描。 光栅对修整装置输出敏感,使得对修整装置输出的曝光导致扫描区域的有效折射率的变化,变化量随扫描速度而变化。 选择要修剪的光栅的区域,并且将扫描速度分布编程到扫描组件中,该扫描组件被计算为沿着其长度修改所选择的光栅区域的有效折射率,以平滑所选择的光栅区域中的组延迟纹波 光栅区域。
