Electro-optical simulation of a GaN based blue LED chip

In this study, an electro-optical simulation method is developed to simulate the light intensity distribution of a conventional GaN based blue LED chip. The entire modeling process consists of electrical simulation with ANSYS and optical simulation with LightTools, which are based on an assumption of proportional relation between the distributed current density and light emission energy on multiple quantum well layer. Experimental results show that the proposed simulation method can give a good prediction on the light intensity distribution of a packaged GaN based blue LED chip.
