Entry knowledge

The subject knowledge on the secondary school level is required.

Rules for evaluation and completion of the course

Evaluation: 1 tests (up to 10), 10 laboratory exercises (up to 20 points). The test has a compulsory written part (up to 50 points) and a compulsory oral part (up 20 points). The content of the exam corresponds to the subject annotation.
Evaluation of activities is specified by a regulation, which is issued by the lecturer responsible for the course annually.


The aim of the course is to acquaint students with basic aspects of optical communications, optical components, optical diffraction and polarization properties of laser beam and laser beam properties. The next goal is to explain the function of optical transmitter and receiver and the principle of the laser function and to analyze optical fiber links, optical wireless links including hybrid and fully photonic links and VLC.
The graduate is able:
- To describe the wave and electromagnetic manifestations of light
- To describe and explain polarization, diffraction and coherence
- To explain the principle of laser function
- To design optical fiber and wireless links
- To compare individual optoelectronic and optical components and discuss their advantages and disadvantages
