Currently the APP’s research in this line is focused on two principal directions. Within the first one, we develop strained silicon-based optical components (waveguides and resonators) for nonlinear optics in the NIR-MIR wavelength range. The second direction is focusing on nonlinear optics with integrated microdisk/microring resonators. As an optically nonlinear material, in this case, Si nanocrystals are used (these are known to have 10 times larger Chi(3) nonlinearities with respect to bulk Si).

The focus of our activity is concentrated on the optimization of electro-optical and thermo-electric properties of silicon nanostructures (silicon quantum dots and silicon quantum wires) for electricity generation and energy harvesting.
