The efficiency of interaction of light with matter is determined by the latters composition and spatial distribution. In fact, the same amount of a certain material but with a different structural arrangement can lead to a very good mirror, (near) perfect blackness, or a mulitcolored spectrum. In the group, we investigate how the spatial configuration of matter on a nanometer scale affects its interaction with light and how these phenomena can be used in the construction of more efficient devices. In our research, we use the knowledge of optics, electrodynamics, and selected elements of solid state theory. We mainly deal with computer modeling and the development of analytical models, and we test our predictions and models in cooperation with the Faculty of Physics as well as with research groups at the Chalmers University of Technology and Universidad Autónoma de Madrid. Our research is part of the global development of functional metamaterials and nanophotonics.

Currently, our research topics include:

Quantum and nonlocal effects in plasmonic nanostructures with the single nanometers size significantly change the resonance properties causing a red or blue resonance shift depending on the plasmonic material (density of conductivity carriers) and the environment. Knowledge of these effects makes it possible to predict the properties of plasmonic systems and devices based on them.

Plasmonic antenna-reactor systems for efficient catalysis, thanks to which we can efficiently use rare catalytic materials such as platinum, palladium, rhodium, and others. By coupling them with optical antennas, we can increase the absorption of light and the generation of hot electrons, which are responsible for the photocatalytic reactions.

Effective properties of the stochastic agglomerates of nanoparticles provide a simple but very effective way to account for optical properties without going into microscopic structural details. The description of two- or multi-component materials comes down to the use of simple, effective electric permeability, which includes all interactions taking place inside the material.

Strong coupling between light and matter opens new possibilities for controlling light, in which hybrid resonances possess properties of both components. It is possible since in this state the energy exchange between the photonic and material subsystems (e.g. exciton) occurs faster than any dissipation. This leads to the emergence of qualitatively new states that make it possible to observe, for example, single-photon nonlinearities, optical logic systems, or to control chemical reactions.

Plasmonic sensors use an amplified electromagnetic field near a metal surface to measure changes of the refractive index that are caused by material and structural changes in that field. These sensors operate based on plasmonic resonance, which occurs for metallic structures with appropriate geometries. Its resonance frequency depends on the size of the structure, material, geometry, and the environment. Changing any of these parameters results in a resonance shift so one can track these changes over time. Very high amplification of the electromagnetic field enables the detection of even single molecules and other effects occurring on the nanometer scale.
