Abstract

A model of optical processes in LEDs was created that takes into account device geometry, light absorption in contacts and cladding layers, photon recycling, light randomization due to surface scattering and the benefit from encapsulation of the device into epoxy. Based on the results of our modeling, an optimization of the LED was proposed. Also, photoluminescence measurements of internal quantum efficiency were performed on the epi-layers used for LED fabrication.
