摘要

本文在自聚焦Kerr非线性介质中提出了一种具有椭圆环结构的pt对称晶格。在纵向调制下，对该势下孤子的存在性和传输特性进行了数值研究。与非pt对称情况不同，该系统中孤子的形状表现出准周期振荡，其传输功率也出现波动。有趣的是，这些孤子的周期和振幅受到初始功率、潜在井深和损益系数等因素的影响。

Power oscillation solitons in PT symmetric elliptical ring potential wells

In this paper, a novel PT-symmetric lattice with an elliptical ring structure is proposed in self-focusing Kerr nonlinear media. The existence and transmission properties of solitons in this potential are numerically studied under longitudinal modulation. Unlike non-PT-symmetric cases, the shapes of solitons in this system show quasi-periodic oscillations, and their transmission power fluctuates as well. Interestingly, these solitons’ period and amplitude are influenced by factors such as initial power, potential well depth, and gain-loss coefficients.
