Abstract

The invention belongs to the field of nonlinear optical research in optical communication, particularly discloses a method for generating a high-power pulse train capable of being transmitted, and provides a simple method for generating a high-power pulse train capable of being transmitted without the continuous background. The method comprises the steps that a specified weakly periodic modulatedcontinuous wave is generated to serves as an initial excited signal; the initial excited signal is input into dispersion decreasing fiber, by adjusting parameters of the dispersion decreasing fiber, the high-power and high-repetition-rate pulse train capable of being transmitted is generated. The method for generating the high-power pulse train capable of being transmitted has the advantages thatthe high-power and high-repetition-rate pulse train capable of being transmitted required in the optical communication can be obtained simply, conveniently and efficiently, and the method has important application value.

Description

technical field [0001] The invention belongs to the nonlinear optical research field of optical communication, in particular to a method for generating high-power pulse trains that can be transmitted. Background technique [0002] With the popularization and application of optical fiber communication, it is an important research goal of optical fiber communication to further increase the communication capacity and extend the transmission distance. In order to increase the communication capacity, wavelength division multiplexing technology is widely used at present. The generation and transmission of high-power ultrashort pulses in a single channel is also crucial to improving the capacity of the channel; due to the loss in optical communication links, it is difficult for pulses with low average power to be transmitted over long distances. Therefore, generating transmittable high-power and high-power pulse trains has become one of the important research directions of optical...
