  • Waveguide for an electro-optic capacitive modulator
    Patent number: 9864255
    Abstract: A waveguide including a substrate, an assembly of semiconductor regions consecutively extending on the substrate along a direction corresponding to a propagation direction of an electromagnetic wave having a wavelength noted ?, the semiconductor regions being electrically alternately doped with a first conductivity type and with a second conductivity type along the propagation direction, a dielectric layer interposed between two consecutive semiconductor regions, at least one pair of consecutive elementary structures having a dimensions along the propagation direction adapted to ? to form a grating where the light propagates with no diffraction effects.
    Type: Grant
    Filed: April 12, 2016
    Date of Patent: January 9, 2018
