AI 中文摘要
本小型综述简要总结了光耦合器中亮孤子的理论及主要实验研究现状，并探讨了进一步的发展方向。光耦合器即双芯波导，结合了芯间线性耦合（平行芯间的光隧穿）、芯内群速度色散与自聚焦克尔（三次）非线性。在对该领域作简短介绍后，本文重点评述了近期双芯非线性光纤中孤子开关的实验结果，以及对称双芯结构耦合器中稳定非对称双芯孤子的自发产生现象。
英文摘要
This minireview provides a brief summary and a discussion of directions for further development of theoretical and, chiefly, experimental studies of bright solitons in optical couplers, i.e., dual-core waveguides which combine the linear inter-core coupling (tunneling of light between the parallel cores with the intra-core group-velocity dispersion and self-focusing Kerr (cubic) nonlinearity. Following a short introduction to the field, the article focuses on a brief review of relatively recent experimental results for the switching of solitons in dual-core nonlinear optical fibers and the spontaneous emergence of stable asymmetric two-core solitons in the couplers with the symmetric dual-core structure.
