This advanced course on optical materials covers functional materials that function based on the interaction between mainly inorganic substances and light, electromagnetic waves, and magneto-optic materials and devices including .
The first half of the course covers the excellent optical properties that arise from the special structure and properties of inorganic materials, as well as the functions and principles of expression of optical materials and elements that utilize them such as optical fiber, optical waveguides, lasers, optical amplifiers, optical resonators, electrooptic elements, and nonlinear optical elements. In the latter half students learn to see things in terms of the correlation between light and magnetism. After relearning about fundamental pehnomena of optics, students learn the magnetic domain observation using Faraday and Kerr effects, tensorial representation of pertimittivity and conductivity, light propagation based on Maxwell equation, consecutiveness of electromagnetic field at interface followed by optical disk, magneto-optical recording, magneto-optical devices for optical communication, advanced devices utilizing magneto-optic materials. Students also learn about metamaterials for creating substances with a peculiar refractive index by controlling electric permittivity and magnetic permeability through the introduction of artificial structures.
By the end of this course, students will be able to:
1) know about the relationships between structure and properties of optical materials.
2) understand the principles of optical wave propagation theory in fiber and waveguide, and the derived functionality.
3）understand the principles of laser oscillation, optical amplification, and their optical phenomena inside the optical cavity structure.
4) know the interaction of electric field with inorganic materials and the induced electro-optical and non-linear optical phenomena.
5) understand the basis of magneto-optic material and know their device applications.
6) understand the basic theory, structures and functions of metamaterial and study a basic guide line to its design.
