Deconvolution of the intrinsic spectrum of AlGaInP microcavity light-emitting diodes

Knowledge of the intrinsic emission spectrum is critical in assessing the performances of microcavity light-emitting diodes. We present a non-destructive method of determining the intrinsic spectra by deconvoluting angle-resolved spectral measurements. Similar measurements on conventional light-emitting diodes confirmed the accuracy of the method.
