A method of thinning the substrate under the junctions has been developed to improve the extraction of light through the front surface of LED's. This new technique has been applied to diodes made by Ga(AsP):N / GaP and Ga(AsP) / GaAs technologies. An increase in efficiency of a factor 3 is demonstrated. A simple theoretical model is presented.
