Estimating the term…
An emissive system including an emissive portion, emitting at a first wavelength, and a lens covering the emissive portion, the lens and the emissive portion being made of a same III-V material, preferably selected from GaN, AlGaN, InGaN and InP, the lens having a core-shell structure with a porous shell, whereby the optical index of the shell is different from the optical index of the core of the lens. The emissive system is obtained according to the following steps: a) providing a structure including an emissive portion emitting at a first wavelength and a lens covering the emissive portion, b) electrochemically porosifying the shell of the lens.
