Abstract
An optical modulator includes a substrate defining a plane and first, second, and third PN junctions formed on the substrate. The first PN junction is formed on the substrate by a first region doped with a p-type doping abutting a second region doped with an n-type doping. The second PN junction is formed on the substrate adjacent to the second region of the first PN junction. The third PN junction is formed on the substrate adjacent to the first region of the first PN junction.
