Optical sources and detectors of radiation
- Department of Microelectronics
The aim of the course is to explain the principle of optical sources, optical amplifiers and photodetectors and their technology. Then discuss their use for informatics and sensors, including optical integrated circuits, both from a theoretical and a broader application point of view. Attention is also paid to components for optical communication and to components for physical and chemical quantities, important measuring and diagnostic methods are given.
