Claim Text:
1. A semiconductor electro-optical phase shifter comprising: a first optical action zone; a first lateral zone and a central zone flanking said first optical action zone along a first axis and having respectively first and second conductivity types so as to form a first diode junction between said first lateral zone and said central zone; a second optical action zone; a second lateral zone flanking said second optical action zone, said central zone also flanking said second optical action zone with said second lateral zone along the first axis, said second lateral zone having the first conductivity type so as to form a second diode junction between said second lateral zone and said central zone; and a first control terminal and at least one second control terminal, said first control terminal being coupled to said central zone and said at least one second control terminal being coupled to both said first and second lateral zones; means for establishing an imbalance between currents flowing in said first and second optical action zones.
