Abstract

The invention provides an all-optical amplification method of an optical soliton pulse train, which belongs to the field of optical technology, and solves the problem that the current way of amplifying the optical soliton pulse train is limited by an amplifier and has certain limitations. The invention utilizes the method of combining plane wave pumping and spectrum filter to realize the direct amplification of the optical soliton pulse train. The amplification process represented by this amplification method has nothing to do with the width of the optical soliton pulse, the central wavelength, the doping concentration of the fiber and other factors, and is applicable to high-order models and fiber systems of different modes. Zoom in directly. The amplification method of the present invention is relatively flexible because it is not restricted by factors such as the parameters of the amplifier.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an all-optical amplification method of an optical soliton pulse train. Background technique [0002] All-optical signal processing has higher speed, lower latency, and greater bandwidth than electrical signal processing. One of the goals of modern nonlinear optics is the development of ultrafast all-optical devices, of which all-optical amplifiers are an important part. Optical solitons are localized light waves propagating in optically nonlinear media that can travel long distances without changing their shape. Due to the potential application in optical communication and optical signal processing systems, a large number of studies on optical solitons have been carried out in the past few decades, such as the existence and stability of solitons, soliton collisions and interactions, and higher-order solitons. With the emergence of the concept of optical solitons, in the early ...
