Abstract
A semiconductor electro-optical phase shifter may include a substrate, an optical waveguide segment (12) formed on the substrate, and first and second zones of opposite conductivity types configured to form a first bipolar junction perpendicular to the substrate. The phase shifter may also include a dynamic control structure configured to reverse bias the first junction and a static control structure configured to direct a quiescent current in the second zone, parallel to the first junction.
