Laboratory of Controlled Optical Nanostructures

The project is devoted to the theoretical and experimental research of hybrid nanostructures. On the basis of this research we will develop new technologies for the creation of ultrathin functional materials and coatings with controllable optical properties for solving applied problems of modern integrated photonics and nanoengineering.

1. Developing the theory of exciton response of nanoparticles formed on the basis of 2D materials accounting for the correlations between the locations of exciton resonances and their dimensions and shapes, the type of layer ordering in the 2D material and their orientation with respect to the symmetry axes of nanoparticles.
2. Developing methods of configuring individual and collective resonance with energy concentration inside the particles and using, for example, bound states in the continuum with amplification or suppression of scattering by readjusting the properties of the layer.
3. Creating models of resonance metasurfaces for concentrating electromagnetic fields in the near wave zone to implement nonlinear effects (highest harmonic generation) and Raman scattering.
4. Describing a method for mode synchronization for the coherent amplification of optical signal in resonatorless systems based on metasurfaces of 2D materials accounting for the overlap of collective exciton resonances.
5. Developing a model of a microlaser relying on a hybrid nanoparticles-TMDC structure.
6. Developing a model of a flat polarization-controlled light filter.
7. Designing metasurfaces with a laser effect based on arrays of nanoparticles of 2D materials accounting for various substrates as well as the methods of their pumping
8. Developing methods of the synthesis and modification of samples in the form of transparent substrates covered with a layer of a 2D materials with semiconductor subwave (for the optical range) nanoparticles placed on its surface.
9. Mastering experimental techniques of laser fragmentation from a solution of 2D materials as well as laser ablation with the surfaces of targets-donors, dichalcogenide transition metals.
10. Observing the optical scattering spectra (and their dynamics) of nanoparticles and their structures on substrates made of a 2D material depending on the control signal.
11. Observing the spectra and dynamics of the resonance modes of nanoparticle scattering (for instance, the Kerker effect, anapoles superscattering and superdirectivity, BIC) and structures made of them depending on the external control signal.
12. Manufacturing samples of metasurfaces of anisotropic nanoparticles with specified period and form factor of separate particles as well as observing the spectra of reflection and transmission of selectively (at a number of wavelengths or in some spectral regions) transparent (anapole and Huygens) metasurfaces modified with TMDC and hBN.
13. Manufacturing composite nanoparticles formed on the basis of various 2D materials.
