Abstract
An optoelectronic device, including: light-emitting sources, each light-emitting source being capable of emitting a first radiation at a first wavelength; photoluminescent blocks distributed into first photo-luminescent blocks capable of converting by optical pumping the first radiation into a second radiation at a second wavelength and second photoluminescent blocks capable of converting by optical pumping the first radiation into a third radiation at a third wavelength; and for each photoluminescent block, an optical coupler including a first photonic crystal at least partially surrounding the photoluminescent block and covering, with the photo-luminescent block, one of the light-emitting sources next to the photoluminescent block, the optical coupler being capable of modifying the propagation direction of rays of the first radiation emitted by the light-emitting source to redirect the rays towards the photoluminescent block.
