Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
That which is claimed is: 1. A semiconductor electro-optical phase shifter comprising: a optical waveguide; a central zone in said optical waveguide and having a first conductivity type, and first and second faces; a structure configured to electrically couple with said central zone; a first lateral zone adjacent the first face of said central zone and having a second conductivity type, the first face configured to form a first diode junction with said first lateral zone;…
