Nonlinear Optics ― Principles and Applications

This book describes the fundamental aspects of nonlinear optics from basic principles to examples of applications. Starting from the polarization induced by an electric field in a material, it related the induced polarization to the propagating fields. The properties of the induced polarization is described through a material response expressed both in the time and frequency domain. This also includes a discussion of the spatial symmetry properties relevant for various materials. The coupling between induced polarization and the propagating field as well as new frequency components generated is discussed on the basis of nonlinear propagation equation.

Karsten Rottwitt received his PhD in 1993 from the Technical University of Denmark (DTU) within propagation of solitons through optical fiber amplifiers. His Post doc was in collaboration with the femtosecond optics group, Imperial College London. From 1995 to 2000 Rottwitt continued at Bell Labs, AT&T and Lucent Technologies, New Jersey, USA. His research was directed toward Raman scattering in optical fibers. In 2000 Rottwitt moved back to Denmark where he is now at the department for photonics engineering, DTU. His research is concentrated on optical fiber nonlinearities including interactions among higher order modes, with applications within bio-photonics, sensing and communication.

Peter Tidemand-Lichtenberg has been working with novel light sources and detection systems for 20 years. He completed his PhD in 1996 from the Technical University of Denmark. After receiving his PhD, he spent six years in small start-up companies developing light sources for various industrial applications. In 2002 he returned to DTU to develop compact coherent light sources in the UV and visible spectral region. He has mainly focused on extending the spectral coverage toward the mid-IR region, and developing efficient light sources and low noise detection systems in the 2-12 μm range based on frequency mixing for the past five years.
