This advanced course on optical materials covers functional materials that function based on the interaction between mainly inorganic substances and light, electromagnetic waves, and magnetic Felds.
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 or electromagnetic waves and magnetism. After learning about device applications related to light and magnetism, students verify the magnetizing behavior and ferromagnetic resonance of the typical high-frequency magnetic material ferrite. 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) know the device application of high-frequency magnetic material and magneto-optical material.
6) understand the basic theory, structures and functions of metamaterial in the micro-, terahertz-, and photonic-wave and study a basic guide line to design metamaterial.
