提出一种分析非平行波导间耦合的简明方法-耦合系数推广法.利用这种方法,导出一种新的非平行双波导的耦合方程,由此得到一组非平行波导耦合的完美的分析解,依据这些分析解可以优化非平行波导的传输距离、输入/输出端口波导间距和夹角.

A concise analytical method (extending coefficient) of coupling between two nonparallel waveguides is reported in this paper. By this method, a novel coupled equations are derived for two non-parallel waveguides. From this, the perfect analytic solutions between two nonparallel waveguides are obtained. In according with these analytic solutions, the propagation distance and spaces of input/output-guide ports and angle may be optimized for the nonparallel waveguide structures.
