Abstract:
An apparatus for controlling a signal includes an optical waveguide having a variable refractive index; an active device formed within the waveguide, the device having three electrodes, a drain, a source and a gate; and wherein the device is located within the waveguide so that current flowing from the drain to the source changes the refractive index.
