设计了用于补偿纯三阶色散的单光纤布拉格光栅。这些器件是通过使用层剥离反向散射技术设计的，并在4.5、6和3 nm的带宽上分别在-20、+/- 40和-225 ps/nm 2的反射带宽上表现出色散分布。此外，它们具有大约75%的几乎恒定的峰值反射率，并且分别仅为8、23和40 mm长。
Single-fiber Bragg gratings designed to compensate for pure third-order dispersion are demonstrated. The devices are designed by use of a layer-peeling inverse-scattering technique and exhibit dispersion profiles across their reflection bandwidths of -20, +/- 40, and -225 ps/nm2 over bandwidths of 4.5, 6, and 3 nm, respectively. Furthermore, they have almost constant peak reflectivities of approximately 75% and are, respectively, only 8, 23, and 40 mm long.
