An optoelectronic light emitting device includes a light emitting diode configured to emit a first radiation, a conversion layer including at least one planar quantum well configured to convert the first radiation into a second radiation, by photoluminescence, a grating for extracting the second radiation being etched on an upper face of the layer, and a lateral reflector having a reflective surface which extends facing part at least of a lateral surface of the conversion layer.

Light emitting device, pixel comprising several such devices, matrix of pixels and associated manufacturing methods

The laser device includes an amplifier including a III-V heterostructure arranged to generate photons, and a waveguide which forms a loop and is optically coupled to the amplifier. The amplifier is arranged facing the waveguide only in the region of a first section of the waveguide.

Laser device having a looped cavity capable of being functionalized

The laser includes an amplifier with III-V heterostructure, designed to generate an optical wave, and a waveguide coupled optically to the amplifier, said waveguide having a hat-shaped cross section, the top of which is proximal to the amplifier. The top of the hat and the lateral sides of the hat are covered with a layer of a dielectric material in the vicinity of the amplifier. The hat is formed by a base and a protrusion of the waveguide, the material forming the base being distinct from the material forming the protrusion.

Heterogeneous laser with high efficiency and method for manufacturing the laser

The invention relates to a method for manufacturing chips composed of at least one electrically conductive material. Such a method comprises the following steps:
