Exact solutions for millimeter‐wave propagation in an optically controlled rectangular semiconductor waveguide were presented. This was implemented by strictly solving the continuity equation that the photoinduced carriers hold and by finite‐difference(SINGLEBOND)time‐domain (FDTD) modeling for the wave propagation in the waveguide. The laser intensity dependence of the millimeter‐wave signal's amplitude and phase shift was obtained. Excellent agreement between numerical results and experiments was found. © 1996 John Wiley & Sons, Inc.
