An optical switching method and apparatus. In one aspect of the present invention, the disclosed apparatus includes first and optical waveguides disposed in a semiconductor substrate layer. An insulating layer disposed between the first and second waveguides in a coupling region in the semiconductor substrate layer to isolate the first optical waveguide from the second optical waveguide. Modulated charge layers proximate to the insulating layer in the coupling region are employed to control an optical coupling strength between the first and second optical waveguides.
