利用自行设计的悬臂梁调节机构 ,对 12cm长的均匀光纤光栅进行中心波长和啁啾的同时线性调谐后 ,将其应用于 2 0Gb/s、10 0km普通单模光纤的色散补偿实验中 ,取得了良好的补偿效果。 Using the self-designed cantilever beam adjusting mechanism, the center wavelength and the chirp of the 12cm long uniform FBG were linearly tuned at the same time, and then applied to the dispersion compensation experiments of 20Gb / s and 100km ordinary single-mode optical fibers. A good compensation effect.
