Nanophotonics is a rapidly developing field of science dedicated to controlling the optical properties of nanomaterials and studying optical phenomena that arise near the diffraction limit. The course allows you to form a picture of modern tools and principles that allow you to manufacture and study various objects on the nanometer scale.

The course is aimed at a wide audience of students planning to work in areas related to nanophotonics.
Not only is it fundamental for experimentalists, but it also provides important background knowledge for theorists. Starting with a discussion of technologies for manufacturing nanostructures and methods for their initial characterization, we will move on to studying methods of optical spectroscopy, interferometry and optical imaging, including super-resolution. In addition to a series of lectures, the course includes laboratory work, laboratory projects, as well as seminars dedicated to discussing the most important achievements of modern science related to optics and photonics.
