Study on the control technology of optical solitons in optical fibers

The control technology of optical solitons has been the applications of all-optical shaping, all-optical switching and signal routing. In optical communications, the dispersion-decreasing fiber (DDF) is used in the control technology of optical solitons. At the same time, when optical solitons are propagated in the DDF, they can form the stable waveforms, which are suitable for long-distance transmission systems. In this paper, with the optical soliton control technology, we study the propagation properties of optical solitons in the DDF. It is found that we can adjust the amplitude of optical solitons, and the amplitude of vibration can be controlled by selecting the appropriate parameters of the DDF. In addition, we can change the transmission mode of optical solitons in the DDF and amplify optical solitons.
