Abstract
This study focused on the development of simulation methodology and design optimization for the DBR(Distributed Bragg Reflectors) structures, which are commonly used in manufacturing optical films and the key components of LED chip and LCD inspection equipments. From the multi-layer simulation, the following results are obtained. First, the wavelength(nm) vs. reflectance(%) can be calculated in the DBR structures that $TiO_2$ and $SiO_2$ thin films are stacked alternately. As a results, it is suggested that highly efficient DBR structures can be designed and manufactured using simulation methodology.
