ABSTRACT:
A method and apparatus for high speed silicon optical modulation is described using a PN diode. In one example, an optical waveguide has adjoining first and second doped semiconductor regions. The first and second regions have opposite doping types and the first doped region extends in two perpendicular directions through the waveguide.
