    In this paper, we present the use of mathematical modeling of dielectric mirror known as known as Bragg reflector for optical design. A device system consists of the identical alternating layers using high and low refractive indices. Results obtained have shown that the model applications such as quarter-wavelength layers, unequal-length layers, short-pass and long-pass filters, and transmission filter design can be simulated and plotted.
