The characteristic of excitation coefficients for an effectively optical coupling
초록
We analyzed the excitation coefficients and the extinction ratio as a function of waveguide width, center to center distance, and angle of input waveguide for a directional coupler. The variation of thc difference between excitation coefficients is similar to that of the extinction ratio. Also, the smaller the difference between those is, the better the extinction ratio is. This concept will have application to devices using optical coupling.
