Current and past research activities in the areas of:

The research focused on studying materials and technological processes for optically passive and active waveguides and other optical components. Amplification of optical radiation and broadening of the amplified optical bandwidth by introducing multiple optical activators such as erbium, ytterbium, and bismuth to create optically amplifying broadband optical components and optical amplifiers.
Activities also include the design and measurement of nanophotonic integrated circuits. Optical nano components for radiation guiding and realization of optical coupling into nanowires. Transmission of these optical nanowires coupled through optical nano-grids and optical nano-tapers.
Another line of research focuses on fiber-optic and planar sensors for fiber-optic local detection of gases and liquids of biological compounds, and planar sensors using nanostructures with surface amplification of the analyte response for Surface Enhanced Raman Spectroscopy (SERS) in the universal and specific detection of chemical and biological compounds, amplification of the interaction with actively trapped organic and inorganic analytes, as well as for the enhancement of physical (e.g. This can be used to enhance both photocatalysis and chemical processes (e.g. polymerization).
Versatile and specialized sensor nanostructures for surface-enhanced Raman spectroscopy (SERS) exploiting surface and local plasmon-polariton phenomena and using these phenomena to enhance physical and chemical processes.
Application of SERS sensors and artificial neural network for the analysis of advanced 2D nanomaterials (MXenes) and biological compounds.
Local detection of gases and liquids using unique (microstructured and tapered) optical fibers.
