FYS-6656 Photonic Materials, 5 cr
Suitable for postgraduate studies.
The course highlights the important role that materials play in modern photonic technologies. It covers light-matter interactions in disordered (photonic glasses), partially ordered (liquid crystals), and ordered (crystalline) materials, as well as in periodic and nanostructured materials, elaborating on the most important use cases of the different materials classes in photonics. The course includes laboratory experiments. Having completed the course, the student is able to - comprehend the fundamentals of photonic materials and understand their design, fabrication and characterization, and interaction with light. - to identify different classes of photonic materials and describe the working principles of photonic devices based on glassy, liquid-crystalline, crystalline, and periodically ordered materials. The student also has knowledge on plasmonic materials and metamaterials, and the role of nanostructuring on the optical response.

Ohjeita opiskelijalle osaamisen tasojen saavuttamiseksi
The total mark is determined based on a final exam, laboratory works, and the student¿s activity in exercise classes. The relative weights of exam and exercise classes/laboratory work/presentation are 50% and 50%, respectively if the student gets at least 45% at the exam.
