Subject description
The course gives an overview of current trends in optoelectronics, then focuses on the technical aspects of modern optoelectronic devices and systems.
In the course the following modern optical sources are discussed: light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs), lasers and laser diodes. Basic control circuits are introduced.
In the context of light detectors, we learn about the operation of a photoresistor, different photodiode soultions, phototransistors and light-sensitive detector arrays (CCD and CMOS). We learn how to connect individual photodetectors to a circuit for reading and further signal processing.
We learn about the basic types of optical fibres and the principle of light propagation through them. We discuss the basic parameters of optical fibres.
We look at the structures and operation of modern displays: LCD, LED LCD, OLED, QLED and microLED.
In the context of photovoltaics, we explore the basics of solar cells and learn about different solar cell solutions and photovoltaic module technologies. We learn about different designs of photovoltaic systems. We go into basic steps involved in the design of a solar power plant.
In the above mentioned areas, students carry out practical exercises in the laboratory and learn about the research equipment of the Laboratory of Photovoltaics and Optoelectronics.
The subject is taught in programs
Electrical engineering 1st level
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 contemporary optoelectronic devices and their structures and to understand their operational principles. Issues important for electrical engineers will be pointed out such as connection of optoelectronic components with other electronic components and circuits. Related to photovoltaics students will learn about the importance of renewable energy sources and the photovoltaics among them, they will learn and think about different technical solutions of PV systems.
Teaching and learning methods
The lectures provide a theoretical background on particular subjects together with presentation of selected practical examples. Handouts of slides are available as well as additional study material. Practical work is devoted to hands-on – working with optoelectronic components.
Expected study results
After successful completion of the course, students should be able to:
- explain basic operational principles of optoelectronic devices
- calculate selected optical and electrical characteristics of devices
- measure basic characteristics of devices
- select an appropriate optoelectronic component for certain application
- design a simple electronic circuit for connection of an optoelectronic device
- carry out basic steps in design of a photovoltaic array for a simple photovoltaic power plant
