Course objectives
Optics of thin films belongs to the importantant branches of physics of thin films. Results achieved within this branch are used in the fundamental research and practice. In this lecture a review of the basic theoretical results concerning optics of thin films is presented. Moreover, main applications of these theoretical results in pratice are introduced as well. In the introduction of the lecture the mathematical (ideal) model of the multilayer systems usable for formulating the theory of optics of these systems within classical (phenomenological) approach is described. Further, formulae for calculating the values of the optical quantities measured in experiments are derived. Thus, the formulae for reflectances, transmittances, ellipsometric parameters and phase changes of the multilayer systems are derived in this part of the lecture. For this derivations two basic approaches are used. The first approach is based on the model of multiple-beam interference of light inside films and the latter one is based on the matrix formulation. Then examples of using the formulae derived for calculating the spectral and angular dependences of the reflectances and transmittances of some multilayer systems employed in optics industry are presented. Furthermore, the basic methods for the optical analysis of the thin films are desribed. It is shown that using the corresponding theoretical approaches and experimental data one determines the values of the optical constants and thicknesses characterizing the multilayer system analyzed. Some methods of the optical synthesis of the thin films are presented too. The methods enabling us to propose the systems with the required values of the optical quantities of some multilayer systems are described. An attention is devoted to the systems forming antireflection coatings, laser mirrors and monochromatic interference filters in transmitted light. An influence of some defects on the values of the optical quantities of the multilayer systems is studied as well. The influence of roughness of the boundaries, columnar structure and transition layers on these quantities is described in detail. In the conclusion the propagation of light within the thin films working as waveguides is explained. Thus, the basic results concerning planar optics is presented. The theoretical results obtained within the lecture are trained through suitable exercises.
