The Design and Calculation of Optical Anti-Reflected and Reflected Multilayer Film

Abstract

This paper gives a brief introduction about the four methods for the structural design of the optical multilayer films, such as the alternated high and low refractive index method, the symmetrical imitated method, the periodic method and the gradient method. Three methods for calculation of the multilayered optical properties are reviewed, including the recursive method, the Fresnel coefficient matrix method and the characteristic matrix method. These three methods are applied to calculate the reflectivity of the anti-reflected and the reflected multilayer film. By using the recursive method, the reflectivity of the anti-reflected multilayer film is obtained as a function of the film thickness and refractive index.
