Soliton self-frequency shift (SSFS), a consequence of Raman self-pumping that continuously red-shifts a soliton pulse, has been widely studied recently for applications to fiber-based sources and signal processing. In this paper, the fundamentals of SSFS are reviewed. Various fiber platforms for SSFS (single-mode fiber, microstructured fiber, and higher order mode fiber) are presented and experimental SSFS demonstrations in these fibers are discussed. Observation of Cerenkov radiation in fibers exhibiting SSFS is also presented. A number of interesting applications of SSFS, such as wavelength-agile lasers, analog-to-digital conversion, and slow light, are briefly discussed.
孤子自频移（SSFS）是拉曼自泵浦的结果，它会使孤子脉冲持续红移，最近在基于光纤的光源和信号处理应用中得到了广泛研究。本文综述了SSFS的基本原理。介绍了用于SSFS的各种光纤平台（单模光纤、微结构光纤和高阶模光纤），并讨论了在这些光纤中进行的SSFS实验演示。还介绍了在表现出SSFS的光纤中对切伦科夫辐射的观测。简要讨论了SSFS的一些有趣应用，如波长捷变激光器、模数转换和慢光。
