Optoelectronic components and systems

Subject description

The following chapters are included in the course:

LIGHT: photon and wave model, complex refractive index, reflection, refraction, scattering, radio- and photo-metry


– Light emitting diodes (LED): direct semiconductors, spontaneous emission, LED structures, practical applications, driver circuits, organic LED (OLEDs)

– Lasers: operational principle, stimulated emission, main parts of a gas laser, optical amplification and losses, spectrum and shape of the output beam, applications of lasers

Laser diodes (LD): structures, operational principle, practical applications (e.g. DVD, Blu ray reader)

DISPLAYS: structure and operation of LCD, LED, plasma and OLED displays

PHOTODETECTORS: semiconductor photodetectors (pn, pin, heterodiode, avalance, phototransistor), circuits with photodetectors, operational principles and structures of CCD, CMOS detector arrays

OPTICAL FIBERS: guiding light in a fiber, single and multimode fibers, attenuation, dispersion

PHOTOVOLTAICS: how a solar cell work, technologies of solar cells and photovoltaics modules, photovoltaic systems, practical steps in design of a solar power plant, examples

5 tasks are conducted from the above mentioned topics within the practice work of the course.  

The subject is taught in programs

Objectives and competences

The objectives of the course are to familiarize students with the state-of-the-art knowledge on optoelectronics and photonics with emphasis on practical realizations of the components and systems. Students learn about the basic operational principles of components and systems and especially how to use them practically.

Teaching and learning methods

The lectures provide a theoretical background on particular subjects together with presentation of practical examples. We put emphasis on practical examples. Handouts of slides are available as well as additional study material. Practical work is devoted to hands-on – working with optoelectronic components and systems.

Expected study results

After successful completion of the course, students should be able to:

  • explain basic operational principles of optoelectronic devices sand simple systems
  • measure basic characteristics of devices
  • select an appropriate optoelectronic component for certain application
  • perform adequate connection of optoelectronic device
  • use photovoltaic components in small photovoltaic systems
