Abstract
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.
