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 λ, 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 λ to form a grating where the light propagates with no diffraction effects.
