皮秒脉冲的非线性光脉冲压缩通常需要长的光纤和多个部件。诸如光纤布拉格光栅的周期性结构在光子带隙之外的波长处是高度色散的。这意味着这种光栅可以用作非常短的全光纤压缩器。在本文中，一些这样的压缩方案进行审查，涉及均匀和非均匀光纤布拉格光栅，依赖于孤子和非孤子压缩的原则。实验结果支持相应的基本理论也被提出。最后，扩展的压缩方案之一，它允许可调的高重复率孤子列车的产生。
Nonlinear optical pulse compression of picosecond pulses typically requires long lengths of optical fiber and multiple components. Periodic structures, such as fiber Bragg gratings, are highly dispersive at wavelengths outside of the photonic bandgap. This implies that such gratings can be used as very short all-fiber compressors. In this paper a number of such compression schemes are reviewed involving uniform and nonuniform fiber Bragg gratings, relying on both soliton and nonsoliton compression principles. Experimental results supporting the corresponding underlying theory are also presented. Finally, an extension of one of the compression schemes is shown, which allows the generation of adjustable high-repetition rate soliton trains.
