Abstract: A semiconductor electro-optical phase shifter may include a first optical action zone having a minimum doping level, a first lateral zone and a central zone flanking the first optical action zone along a first axis, doped respectively at first and second conductivity types so as to form a P-I-N junction between the first lateral zone and the central zone. The phase shifter may include a second optical action zone having a threshold doping level, and a second lateral zone flanking the second optical action zone with the central zone along the first axis doped at the first conductivity type so as to form a P-I-N junction between the second lateral zone and the central zone.
