摘要:

结果表明,具有增益和损耗的非对称波导可以支持光束的稳定传输。这意味着相应复光学势的模式传播常数是实的。一类这样的波导被发现从两个光谱问题之间的关系。一个特殊的例子,非对称波导,所描述的双曲函数,进行了分析。证明了线性模式和非线性模式的连续族的存在性和稳定性。

英文摘要:

It is shown that asymmetric waveguides with gain and loss can support a stable propagation of optical beams. This means that the propagation constants of modes of the corresponding complex optical potential are real. A class of such waveguides is found from a relation between two spectral problems. A particular example of an asymmetric waveguide, described by the hyperbolic functions, is analyzed. The existence and stability of linear modes and of continuous families of nonlinear modes are demonstrated.
