Abstract
In accordance with the present invention, an elongated phase shifting diode is provided for modulating an electrical signal onto an optical wave. Structurally, the phase shifting diode includes a p doped central stripe that extends through a phase shifting length L of a waveguide. Pdoped finger stripes and Ndoped finger stripes, which are laterally and axially offset from each other, extend into the waveguide for contact with the p doped central stripe along the length L. In combination, the plurality of Ndoped finger stripes and the p doped central stripe create a plurality of PN junctions that are structurally aligned along the p doped central stripe to establish electrically parallel phase shifting functions for the elongated diode.
