Abstract : Theoretical analysis of three fundamental deficiencies of optical thin films is studied: the effect of the extinction coefficient of the refractive index, surface roughness effects, and refractive index nonuniformity on the propagation attenuation of thin film waveguides. Based on different deficiencies in the propagation attenuation of different guide nodes in optical thin films, the article presents a method of distinguishing absorption and scattering losses in thin films.
