Course: Elements of Photonics 1

Department/Abbreviation: SLO/ZF1

Year: 2021

Guarantee: 'prof. RNDr. Jan Peřina, Ph.D.'

Annotation: Basic knowledge from the area of modern photonics will be provided to the student. Attention will be paid to various sources of radiation, especially to lasers. The principle of a laser will be elucidated using kinetic model. Numerous laser applications will be discussed. Elements of nonlinear optics will be studied, different nonlinear processes will be quantified. The possibility to generate nonclassical states of light in these processes, namely squeezed states and states composed of photon pairs, will be mentioned. Their use for fundamental physical experiments and in metrology will be discussed. Excursion to laboratories of nonlinear quantum optics will occur at the end of the lecture.
