Course Description

The course is an introduction into the technology and principle of information transmission using light signaling. Following a discussion on physical foundation of light emission and detection, the course presents operating principles of main components in the fiber optic communications chain (lasers, modulators, optical fibers, and optical receivers) and discusses the main phenomena that degrades the quality of information transmission. Examples are given for optical communication and sensor systems and relevant components.
