Learning Outcomes
After passing the cours, the student knows the basic optical properties of thin films and waveguides as well as their mathemetical analysis. The course starts by a brief review of electromagnetic waves and their behaviour at interfaces. Next optical properties of single- and multilayer films are analyzed by the transfer-matrix method. Emphasis is on understanding optical structures which can be realized using thin films. These include anti-reflections coatings, dielectric mirrors, beam splitters, optical filters and polarizers. Thin films are then analyzed as waveguides. Most important characteristics of waveguide modes of metal/dielectric waveguides and optical fibers and their numerical evaluation is introduced. Also surface plasmon polaritons, distrubuted Bragg gratings and directional couplers are analyzed to understand their possibilities in photonic integration. Matlab is extensivelly used to solve the exercises, visualize the optical fields and optimizing the structures.
