This course gives an introductory into the optical properties of solids. The fundamental principles of absorption, reflection, luminescence and light propagation are discussed for a wide range of materials, including crystalline insulators, semiconductors, and metals. Classical and quantum models are used as appropriate, and the observed phenomena are discussed from point of their application.

Syllabus of lectures:

1. Interaction of electromagnetic wave with solids

2. Fresnel's equations for isotropic and anisotropic media

3. Optical properties of uniaxial and biaxial crystals, birefringence

4. Phenomenological theory of electrooptical, piezooptical and magnetooptical solids

5. Einstein coefficients

6. Quantum theory of optical absorption and emission, joint density of states

7. Band edge absorption in direct and indirect gap semiconductors, band edge absorption in external electric and magnetic fields, interband absorption above the band edge, semiconductor photodetectors.

8. Wannier (free) excitons and Frenkel (tightly bound) excitons, exciton absorption, free excitons in external fields

9. Luminescence, configuration curve model, Franck-Condon principle, fluorescence, phosphorescence, luminescence in direct gap and indirect gap materials, photo- and electroluminescence, photoluminescence spectroscopy

10. Quantum confinement, quantum-confined structures, electronic levels, quantum well absorption and excitons, optical emission

11. Free electrons, plasma reflectivity, Drude–Lorentz model, metals, doped semiconductors, plasmons, negative refraction

12. Molecular materials, optical spectra of molecules, conjugated molecules, organic opto-electronics, carbon nanostructures

13. Nonlinear optics, the nonlinear susceptibility tensor, the physical origin of optical nonlinearities, second-order nonlinearities, phase matching.
