Propagation properties of quasi optical soliton and communication technology

摘要: 对准光孤子理论进行了研究，用一个合适的、持续的色散管理方法，从一个修正的非线性薛定谔方程得到一个精确解，用这个解构造一个非线性稳定的准光孤子脉冲。用数值模拟的方法得出了准光孤子和光孤子的波形。结果表明：准光孤子几乎具有光孤子的全部优点，其脉冲宽度比光孤子要小很多，并且准光孤子的脉冲宽度可以通过调节光纤的结构参数来进行调整，准孤子能够在光纤中稳定地实现长距离传输，而且能够很好地克服由孤子的固有特性造成的对通信容量的限制，所以准光孤子有望成为下一代通信系统的最佳信号载体。

Abstract: Combination of programmed chirp and dispersion profiles produced a quasisoliton nonlinear pulse with a stable structure. With the nonlinear effects taken into account, the concept of quasisoliton is introduced and the comparison between the quasisoliton solution and the soliton solution is made. Compared with soliton, quasi optical soliton has more advantages, such as reduced interaction, smaller peak power and pulse width adjustable by modulating fiber parameters. Quasisoliton transmission has great potential in next generation of communication system.
