Abstract:
A semiconductor electro-optical phase shifter may include a central zone configured to be placed in an optical waveguide and doped at a first conductivity type, a first lateral zone adjacent a first face of the central region and doped at a second conductivity type, and a second lateral zone adjacent a second face of the central zone and doped at the second conductivity type.
