Research at the Department of Optoelectronics

The Department of Optoelectronics carries out research and implementation work in diagnostic methods, photonics, materials engineering, and measurement systems. Our aim is to develop solutions that support science, industry, and medicine, and that address problems of safety, environmental protection, and human health.

Main research areas

1. New materials for sensors and future electronics

We synthesise and study semiconductor materials such as carbon thin films, boron-doped diamond, and black phosphorus. Their properties make them suitable for sensors that detect toxic compounds, hazardous substances, and biological pathogens.

2. Fibre-optic sensors, from modelling to construction

We develop sensors that detect small changes in temperature, pressure, strain, and chemical composition. They are immune to electromagnetic interference and can operate under extreme conditions, from the interior of industrial reactors to biomedical applications.

3. Non-invasive imaging (Optical Coherence Tomography, OCT)

Using optical interferometry, we examine the internal structure of materials and biological tissues without damaging them. OCT is applied in medicine (diagnostics of the eye, skin, and circulatory system) and in the analysis of advanced materials.

4. Optical and electrical measurement systems

We build and integrate measurement systems based on electrical, electrochemical, and photonic methods. We use instruments from leading manufacturers (Keithley, National Instruments, Keysight, Tektronix, Ando, Newport, Thorlabs) together with our own electronic circuits designed around microcontrollers, digital signal processors, and FPGAs. We also develop embedded solutions based on single-board computers (Raspberry Pi) and microcontroller platforms (Arduino, STM32).

5. Advanced diagnostic methods

Our work uses, among others:

  • impedance spectroscopy for monitoring corrosion processes
  • optical coherence tomography (OCT) for non-invasive studies
  • spectral methods (absorption, Raman) for detecting chemical and biological substances
  • spectrophotometry and optical analysis for assessing the quality of materials and technological processes

6. Information visualisation systems and artificial intelligence

We design measurement systems integrated with wireless communication (Bluetooth, ZigBee, LoRa) and develop signal-processing algorithms (PCA, SVM, deep learning). This makes it possible not only to record measurement data but also to analyse it. We also use VR/AR technologies and holography to visualise results and to build new diagnostic tools.

Research projects and international collaboration (link)

We run projects on gas sensors, fibre-optic sensors, and systems for detecting viruses and other biological agents. We collaborate with research centres worldwide and with companies in the region, which gives students the opportunity to take part in research with practical and social relevance.

Why join us?

Students at the Department of Optoelectronics can take part in interdisciplinary research at the boundary of electronics, photonics, and materials engineering. Taking part in our projects means:

  • working with modern research instruments
  • gaining experience in material synthesis and sensor construction
  • practical training in programming measurement systems and in artificial intelligence
  • collaboration on national and international projects
  • the possibility of applying research results in industry

We believe the future belongs to optoelectronic technologies. Join us and help build it.
