Course description and aims

In this course, the instructor will explain various behaviors of light, including light propagation, optical transition, and light-mater interactions, in solid-state media. First, basic optical properties of conventional uniform media and typical anisotropic/magneto-optical crystals will be explained, and then explain how such properties change in periodic media, metallic structures, and electric circuits. The students will learn what determines the optical properties of materials and how they are limited. Furthermore, they will learn how these limitations can be overcome by introducing nanostructures.

Student learning outcomes

At the end of this course, students will be able to
(1) understand how optical dispersion and optical transition are determined in various solid-state media
(2) understand basics and characteristics of optical waveguides and optical resonators
(3) understand the origin of limitations for light confinement strength, light dispersion, and optical transition rate in conventional media
(4) understand those limitations can be overcome by introducing wavelength-scale periodic structures, metallic nanostructures, and nano-circuit elements.
