Abstract
An optoelectronic device includes a LED that is suited to the emission of a radiation and that includes an active layer, and a conversion layer that extends over the active layer of the LED and that includes a plurality of fluorophores suited to the conversion of the radiation emitted by the LED, wherein the conversion layer is confined laterally by a mirror reflecting both the radiation converted by the fluorophores and the radiation not converted by the fluorophores, and vertically between a first and a second multilayer reflective filters forming a resonant Fabry-Perot cavity that blocks the radiation not converted by the fluorophores and has a transmittance peak for the radiation converted by the fluorophores.
