Nonlinear Optics

What it is about

You learn the physical foundations and models of nonlinear optics (classical and quantum-mechanical), the symmetry properties of nonlinear susceptibilities, and the description of interactions between light fields in materials. In the end you can design basic nonlinear optical systems and analyze their performance, e.g. frequency converters, parametric amplifiers/oscillators, electro-optic modulators and Raman-based systems.

What you will be able to do

• Understanding the causes and mathematical description of optical nonlinearities
• Applying classical and quantum-mechanical models to nonlinear processes
• Analyzing the symmetries of nonlinear susceptibility tensors
• Formulating and solving coupled wave equations and evaluating phase-matching
• Design and analysis of systems with second-order nonlinearities (SHG, SFG, DFG, OPA, OPO, electro-optic effects)
• Design and analysis of systems with third-order nonlinearities (self-focusing, SPM, Raman- and Brillouin-effects, optical solitons, multiphoton absorption)
