| NFYD77 | Material Optics, 7 ECTS-points /MATERIALOPTIK/ Advancement level: D | |
| Aim: The purpose of the course is to give the physical background to linear and non-linear optical properties of solid materials and to give examples of how these properties can be used in measurement methods, optical components and systems.Prerequisites: Participation in NFYC58 Quantum Mechanics and Molecular Physics, NFYC56 Solid State Physics.Course organization: The course consists of lectures during which the most important theory is discussed. Some of the lectures are devoted to problem solving. A laboratory course will be included. The course will be in English if required.Course content: Linear optics: Optical response of homogeneous materials - the dielectric function, the complex index of refraction, Clausius-Mossotti's equation, Kramers-Kronig transformations, anisotropic materials, the Lorentz, Drude, empirical and quantum mechanical models. Inhomogeneous materials - effective medium theories, Maxwell-Garnett, Bruggeman, effects of particle shape, limit theorems. Polarized light - plane waves, polarization, Jones vectors and matrices. Reflection - Fresnel's laws, total internal reflection, evanescent fields, surfaces with layers, matrix formalism for multilayered surfaces, anisotropic layers. Methods - ellipsometry, surface plasmon resonance. Non-linear optics: The dielectric function for non-linear response. Electromagnetic propagation in anisotropic materials, Gaussian optics. Fundamental concepts of non-linear optics. Frequency conversion and the electro-optic effect. Effects of intensity-dependent index of refraction and non-linear absorption and transmission coefficients. Effects of crystal symmetry on response functions. Electro-optical modulators. Phase matching in frequency conversion. Non-linear diffraction of gaussian beams.Course literature: Thin Film Optics, H. Arwin and reprints. | ||
