Abstract
The field of the invention is that of optoelectronic components with a buried stripe structure. The optoelectronic device according to the invention is a stripe structure, comprising at least one buried waveguide and a layer called a grating layer in the form of an elongate stripe comprising features, each feature having an approximately rectangular shape, the length of the feature being substantially perpendicular to the direction of the length of the stripe of the grating layer, the layer being placed so as to provide optical coupling with an optical wave propagating in the waveguide, the length of certain features being substantially less than the width of the waveguide.
