ECE 598: FUNDAMENTALS OF LIGHT-MATTER INTERACTIONS
2020 Fall; 2021 Fall; 2022 Fall
This course will provide an overview of how light interacts with materials. Although such interaction is most rigorously described using quantum mechanics, the approach used here is mainly classical. We will first introduce classical dipole oscillators coupled with Maxwell’s equations. We will study the linear optical properties (dielectric function, susceptibility, refraction, dispersion, and absorption) of gases, liquids, and solids, including metals, semiconductors, and dielectrics. We will also study dispersion relations, which allow us to completely describe the dielectric function of materials by only measuring the full spectrum of a single property. We will consider how quantum mechanics modify our picture of the optical properties of materials. The effect of magnetic polarization will be considered, as we look at the optical activity and Faraday rotation. In addition, we will study nonlinear contributions to the polarization, and understands how this leads to the generation of new frequencies and to irradiance-dependent refractive index and absorption. Finally, we will introduce the unique interactions of light with nanoparticles, photonic bandgap materials, and artificial materials such as metamaterials.

ECE 570: NONLINEAR OPTICS
2021 Spring; 2023 Spring
Nonlinear optics allows us to change the color of a light beam, to change its shape in space and time, and to create the shortest events ever made by humans. Nonlinear optical phenomena are the basis of many components of optical communications systems, optical sensing, biomedical imaging, and materials research. This course introduces the fundamentals and applications of the nonlinear interaction of radiation with matter. The goal is to provide a working knowledge of nonlinear effects, nonlinear materials, and the applications of nonlinear optics in various technologies.
