Abstract :
The finite-difference time domain (FDTD) method for dispersive media is applied to the study of the electromagnetic wave propagation in optically-controlled coupled-dielectric-waveguides. The optical control is achieved by means of light incidence on semiconductor layers deposited onto the waveguides. The effects produced by the induced plasma in the semiconductor are analyzed through the dispersion characteristic of the waveguide structure
