Paper Abstract

In this paper, based on the Monte-Carlo ray tracing simulation we present the study of the light extraction efficiency of GaN-based LEDs as a function of the position of the light source over the active layer with several parameters, including chip dimensions, absorption coefficients and package. Besides, the light extraction efficient characteristic of a ThinGaN LED is studied.
