OPTOELECTRONIC COMPONENT

An optoelectronic component for integration into an optoelectronic circuit includes a III-V semiconductor membrane, a P-doped layer, an intrinsic layer deposited on the P layer, and an N-doped layer, deposited on the intrinsic layer; an asymmetrical photonic crystal waveguide, formed in the membrane by a two-dimensional photonic crystal on one longitudinal side and by a face with total internal reflection on the other longitudinal side; contacts arranged on either side of the PhC waveguide, for injecting electrical charge carriers into the PhC waveguide laterally with respect to the membrane; the layers arranged such that the intrinsic and N layers only partially cover the P layer, forming a side face extending perpendicularly from the surface of the P layer, a portion of the side face forming the face with total internal reflection of the PhC waveguide; the PhC waveguide is evanescently coupled to a passive semiconductor waveguide in a coupling region.
