摘要
本文根据非正交模理论导出了描述光栅作用下双波导间反向耦合的耦合模方程组.通过数值计算对这种结构的反向耦合特性进行了初探,并同光栅作用下单波导反向耦合特性作了比较.
A coupled wave equation set discribing the grating assisted double-waveguide contra-directional coupling is derived based on the nonorthogonal coupled mode theorem (NOCMT). Through numerical computation, the coupling characteristics are finalized and compared with those of a grating assisted single waveguide contra-directional coupling,
