The objective of the course is to present a basic overview of nanophotonics including the underlying principles and some current trends. The attendees will be able to understand the light-matter interaction at nanoscale as well as the to study new and potential subwavelength applications.
Physics: basic knowledge in fields of optics (ray optics, interference and diffraction of light, principle of laser), electrodynamics (Maxwell equations, wave equation, plane wave, waves in optical materials) and semiconductor physics (energy bands, p-n junction).
Mathematics: ability to solve simple partial differential equations.
Course contents summary
The course provides an introduction to the newly developing and fascinating area concerned with controlling light at a subwavelength scale. Topics of discussion include: near-field optics, nanoscale quantum emitters, photonic crystals, plasmonics and optical metamaterials. Where necessary, selected elements of related concepts, such as diffraction theory, light-matter interaction, interaction with small structures, and nonlinear optics, are provided too.
