Expertise in plasmonics; nonlinear optics; metamaterials; and nanooptcis. Current research includes:
- Laser-induced periodic surface structure (LIPSS). The effect of the LIPSS formation is interesting for fundamental physics and for practical applications, the mechanisms of the pattern formation are still not completely clear. Some theories try to explain the laser-induced periodic structures. One of them describes the LIPSS formation as an interference between the incident laser beam and the surface plasmons excited on the surface during the laser ablation, however, the validity of the plasmon excitation conditions by laser ablation is controversial. Our research focuses in the investigation of the origin of the LIPSS formation.
- Metasurfaces. Nanostructured surfaces are engineered2D composites with unprecedented capabilities of controlling light propagation, the aim of this work is to study theoretically and experimentally the potential of the metasurfaces to develop and prototype novel opto-mechanical mechanism for trapping and manipulation of particles.
