Abstract
From the reflection and transmission of light in coupled slabs, we derive t he coupling coefficient of modes in coupled waveguides. The present result is found to be similar to that of the conventional coupled-mode theory whic h requires the evaluation of the overlap integral of modes in each individu al waveguide, pur method is simple, especially for analyzing complicated co upled waveguides.
