非对称有源耦合器：稳定的非线性超模和定向输运
The Asymmetric Active Coupler: Stable Nonlinear Supermodes and Directed Transport
摘要：
本文研究了由两个具有增益和损耗的异质波导耦合而成的非对称有源耦合器。我们表明，在一般的条件下，不受宇称时间对称性的限制，存在有限的功率，恒定强度的非线性超模（NS），导致增益，损耗，非线性，耦合和相异性之间的平衡。该系统具有非互易动力学，使定向功率传输和光学隔离功能。
英文摘要：
We consider the asymmetric active coupler (AAC) consisting of two coupled dissimilar waveguides with gain and loss. We show that under generic conditions, not restricted by parity-time symmetry, there exist finite-power, constant-intensity nonlinear supermodes (NS), resulting from the balance between gain, loss, nonlinearity, coupling and dissimilarity. The system is shown to possess nonreciprocal dynamics enabling directed power transport and optical isolation functionality.
