Course Overview

The basic principles of optical responses of solid state materials are explained based on both electromagnetic and quantum theories. The lectures cover the light dispersion in matter, optical constants, Lorentz oscillator model, Kramers-Kronig analyses, optical spectra, optical transitions, Fermi's golden rule, light absorption/emission, optical properties of semiconductors, exciton, etc.

Learning Achievement

Students study the optical response of solids from an electromagnetic and quantum theory point of view. Students need to understand how the two views are linked, as well as the properties required for optical materials based on this.

Competence

"Basic Knowledge of Engineering", "Basic Academic Skill", "Expertise", "Ethics", "Practical Insight and Problem Solving"

Course prerequisites

To understand the quantum-theoretical handling of optical responses, quantum-mechanical knowledge, such as perturbation theory and quantization of emission fields, are necessary. It is difficult to understand the optical properties of a solid without knowledge of solid-state physics (especially, solid-state electron theory, band structure, etc.). Consequently, students should have completed subjects related to these topics before taking the course.

Grading Philosophy

1) Evaluation method: Results will be evaluated based on reports submitted for all the lectures (Report 100%).
2) Evaluation criterion: Proper and sufficient answers and descriptions should be given to questions or issues.
