ABSTRACT:
An optical mode converter comprising a slow wave electrode structure and including Schottky barriers for preventing an accumulation of free carriers in the optical waveguide region of the converter. The Schottky barriers are also used for suppressing higher order modes in the waveguide. Low refractive index insulators are used to allow efficient driving of the device without hindering the impedance or the microwave index of the optical mode converter. Two-photon absorption processes are eliminated through the use of a waveguide semiconductor material having a bandgap of at least twice the photon energy of the light beam propagating through the optical mode converter.
