Abstract

In this paper, the coupling coefficient between two adjacent waveguides with conducting interfaces is calculated analytically. It is shown that the presence of interface charges, their density being controlled via a transverse voltage, leads to the control of the coupling. TO derive the coupling coefficient, the basic Coupled Mode Theory (CMT) with paraxial approximation is improved to include the effect of conducting interfaces. The analysis is performed independently for TE and TM polarizations. Several direct applications of this effect such as multiplexer, coupler and Mach/Zhender modulator/switch and programmable grating are introduced
