Abstract
Device successively including a substrate including a metal layer capable of reflecting a radiation; a first layer of a III/N type alloy, p-type doped, and including a first surface, opposite the metal layer, the first surface being provided with cavities; a light-emitting layer made of a III/N-type alloy, capable of generating the radiation; a second layer of a III/N-type alloy, n-type doped, having the radiation coming out therethrough; wherein a non-metallic filling material transparent in the spectral range is arranged within the cavities.
