Manufacturing process for an emissive system

Abstract

Method for manufacturing an emissive system The present description relates to an emissive system (100) comprising an emissive part (120), emitting at a first wavelength, and a lens (135) covering the emissive part (120), the lens (135) and the emissive part (120) being of the same III-V material, preferably chosen from GaN, AlGaN, InGaN and InP, the lens having a core-shell structure with a porous shell (136), whereby the optical index of the shell (136) is different from the optical index of the core (137) of the lens (135). The emitting system (100) is obtained by the following steps: a) providing a structure (100) comprising an emitting part (120) emitting at a first wavelength and a lens (135) covering the emitting part, b) electrochemically porosifying the shell (136) of the lens (135).
