Course content

This course contains the physics of the interaction of light with materials, advanced polarization description of light, classical thin film optics modelling and introduction to Computational Electro-Magnetics (CEM). An overview of linear and non-linear state of the art spectroscopy and imaging methods in material science and bio-optics. The course includes a practical hands-on introduction to spectroscopic ellipsometry and modelling of optical properties of complex materials structures (e.g. multilayers stacks such as solar cells, quantum wells, antireflection coatings etc).
- The Jones formalism and the description of fully polarized light will be briefly reviewed, with emphasis on the more general Stokes-Mueller formalism, depolarization and partially polarized light and methods for analysis of the Mueller matrix, and the application to analyzing/designing polarization sensitive spectroscopy and imaging methods, such as e.g. the spectroscopic ellipsometer.
- The physics of the interaction of light with materials is a core component of the course. The course deals with principally linear optics, but with an introduction to nonlinear optics, in addition to a description of luminescence and fluorescence. The physics behind the dielectric function in the range Thz-IR-VIS-UV and VUV is given, and how functional properties in terms of solar cells, lasers, Light Emitting Diodes, can be optimized by careful control of the dielectric function. The relationship between quantum mechanical models for optical absorption and the dielectric function, and the discussion of practical dispersion models for phonons (vibrational spectroscopy in IR), rotational spectroscopy (IR-Thz), free carrier response, and electronic band to band absorption of amorphous and crystalline media.
- A model for temporal and spatial coherence is presented and related to the polarization state of light, and the FTIR and OCT techniques.
- We present the formalism for modelling the optical response from plane isotropic, anisotropic, electro-magnetic, and bi-anisotropic layers: The airy formulas and the 2x2 Abeles transfer matrix theory for isotropic materials, and the 4x4 Berreman transfer matrix theory for anisotropic electro-magnetic and generally bi-anisotropic materials. Therein understanding of chirality, the Faraday effect, the Kerr effect, magnetic materials and artificial meta-materials. Optical coatings will be studied and particular attention will be made on Bragg mirrors and discussed together with an introduction to photonic crystals.
- We present the closed form solutions for modelling spherical and spheroidal particles (Mie Theory) where the quasi-static approximation is outlined in detail.
- An introduction to nano-plasmonics and applications and effective medium theories (electromagnetic mixing theories) in relation to inhomogeneous materials through effective medium theories of granular media (including nanostructures) will be treated in detail.
- Modeling, excitation and applications of Surface Plasmon Polaritons (SPPs) and Localized Surface Plasmon Resonances (LSPR) will be discussed in detail. Applications of COMSOL simulations (in 2017) versus quasi-static models.
- Meta-materials and a discussion of selected applications. Models for artificial chirality and artificial magnetism.
- Periodic structures such as photonic crystals and diffraction gratings are discussed and the Rigorous Coupled Wave Analysis method is outlined.
- Introduction to the modelling of random surfaces, surface roughness
- Introduction to Non-linear optics and spectroscopy, the nonlinear optical susceptibility tensor, and concepts in advanced imaging using non-linear spectroscopy.
