摘 要: 本文研究了随机反应的强非局域介质中部分非相干线性孤子的传输特性,基于线性传输方程和互谱密度理论,得到了此类非相干线性孤子的解析表达式。入射光束的功率以及光束的相干特性决定了孤子半径的表达式。在强非局域介质中光束的传输模式是线性的,因此孤子的形成过程中不存在一个非相干的阈值。本文详细讨论了孤子进行线性谐振时的光束半径以及光束相干特性的演化过程。
关 键 词: 无线电物理;非相干孤子;强非局域介质;互相干函数法

Abstract: This paper studies the propagation of incoherent accessible solitons in strongly nonlocal media with arbitrary response function. Based on the linear propagation equation and the mutual coherence function approach, an exact analytical solution of such incoherent accessible solitons is obtained. The solitons radius is related to the total power as well as the coherence characteristics of the incoherent beam. The result shows that there is not a threshold for incoherent solitons exist in strongly nonlocal media because the model is linear. Evolution behaviors of the solitons width and the coherence radius are also described when the solitons undergo linear harmonic oscillation.
Key words: radio physics; incoherent solitons; strongly nonlocal media; mutual coherence function approach
