Analysis of light-emitting diodes by Monte Carlo photon simulation

A Monte Carlo photon simulation method, which is based on statistical traci ng of photons inside the chip, has been developed for analysis of LED's in quantitative terms. Also included in the analysis is practical modeling of textured surfaces, which are often employed for enhanced Light output. The method with its unique versatility is applicable to virtually any chip geom etry and measures various important parameters such as photon-output-coupli ng efficiency, detailed photon flight statistics, and photon-output distrib ution patterns. It is speculated that the method can easily be extended to development of LED lamps and packages. (C) 2001 Optical Society of America.
