摘要: 本文提出了分析包含非线性介质的层状介质波导特性的等效传输线方法。通过把线性和非线性介质分别用等效传输线表示,从而把非线性介质这一复杂的电磁场问题等价成一个电路问题求解。其本征方程可以利用横向谐振原理得到。本文最后分析了层状介质波导包含饱和和非饱和非线性介质时TE模的传播功率与归一化传播常数之间的关系。所获得的结果与有关文献符合得相当好。

Abstract: This paper presents a so called equivalent transmission line method for the analysis of multilayer dielectric waveguide involving nonlinear dielectric. By introducing the equivalent transmission line model of nonlinear dielectric and linear dielectric, the electromagnetic field problem about the nonlinear dielectric waveguide can be equivalent to a circuit problem. The eigen-equation governing the nonlinear dielectric waveguide can be obtained by using the transversal resonance technique. Finally, the multilayer dielectric waveguides involving saturable or non-saturable nonlinear dielectric are simulated, and the relations between the propagating power of TE mode and the normalized wavenumber are given. The results obtained are in good agreement with that in the references. -
