摘要

提出了一种计算光介质波导特性的积分方程-有限元法。该方法适用于芯形任意、芯折射率和包层折射率分布任意的光介质波导。得到了宽高比在1.0 ~ 100.0范围内的矩形、椭圆、圆角矩形波导和凹芯波导的截止频率。

The combined IEM-FEM method for calculation of properties of optical dielectric waveguides with arbitrary core near the cutoff

The combined method of integral equation - finite elements (IEM-FEM) has been developed for calculation of optical dielectric waveguide properties. The method is applicable for optical dielectric waveguides with arbitrary core geometry and arbitrary distribution of core index of refraction and the constant cladding index. The cutoff frequencies are obtained for rectangular, elliptical, "rounded rectangle" waveguides and waveguides with concave core shape for aspect ratio from 1.0 to 100.0.
