Abstract

The lecture provides an introduction to the fascinating field of Nonlinear Optics. It is shown how light waves can interact in certain materials. The relevant effects as well as the structure and the properties of the required materials and a selection of applications (optolectronics, optical signal processing) will be treated.

Objective

The lecture provides an introduction in the field of Nonlinear Optics and will bring the students up to date with current research work as it is also carried out in the Institute of Quantum Electronics.

Content

The lecture provides an introduction to the fascinating field of Nonlinear Optics. It is shown how light waves can interact in certain materials. These effects are important for applications in optoelectronics and optical signal processing and as investigation methods in basic research. The relevant effects as well as the structure and the properties of the required materials and a selection of applications will be treated in the lecture. • Introduction to the linear and nonlinear light-matter interaction • Introduction to crystal optics • Fundamentals of nonlinear effects in molecules and solid state materials • Nonlinear optical materials and their applications in laser technology and telecommunications • Optical frequency-doubling, optical sum- and difference-frequency generation • Optic parametric oscillation • Light-light interactions and optical switching • Four-wave mixing, self-phase modulation, self-focussing, spatial and temporal solitons
