Abstract

An optical phase shifter is described, which includes an optical waveguide which is realized in a substrate and has an optical conduction surface within the substrate, the optical conduction surface including at least a first region having a first doping and at least two second regions having a second doping that differs from the first doping. The first region is situated between the two second regions.
