About us

The research topics of DO cover two areas:

  • Physical and chemical optoelectronic and acoustoelectronic sensors
  • Fiber and planar optoelectronics

DO has the equipment to analyse conjugated receptor materials and sensor structures by simultaneous, comprehensive measurements using several techniques. Among other things, it is possible to characterize structures using AFM, CLSM, SNOM microscopic techniques, and Raman and SEM spectroscopy. Metrological laboratories also enable the determination of optical parameters of sensor structures by methods of surface plasmon spectroscopy and spectral ellipsometry under the exposure to gas mixtures containing the tested gas analyte at a varying concentration and in varying environmental conditions. The stations with precise gas mixers are used to generate the tested environment.

DO is also equipped with measuring equipment for acoustic emission measurement and optical magnetometry, which allows studies of the magneto-optical effect of glasses and optical fibers in constant and variable magnetic fields.

In addition, DO has technological facilities with fume hoods, laminar chambers as well as photolithography and vacuum technology of applying thin layers for implementing various configurations of sensor structures. These structures also include fiber optic and waveguide systems produced using ion diffusion and sol-gel techniques.

The key achievements of DO concern:

  • production and characterization of sensor materials,
  • manufacturing and testing of structures and photonic, micro- and optoelectronic transducers and measuring systems based on them,
  • signal processing in optical, photonic, resistive and acoustoelectronic transducers and measuring structures,
  • photonic methods of cancer diagnostics and optical methods of artificial heart chamber diagnostics,
  • research and characterization of low-dimensional carbon structures: graphene, graphene oxide and graphite oxides.

Over the past several years, DO has implemented over twenty centrally funded projects, and the measurable effect of the research is the publication of several hundred articles in world-wide recognized journals with a high scientific rank, 5 national patents and 6 patent applications. KO cooperates with numerous companies in the fields of gas, photonic and microelectronic sensors as well as measurements of physical quantities.
