Current research topic (PhD)

“Optomechanics in the photonic crystals”

The PhD work is focused on the implementation and investigation of optomechanical interactions in conventional 2D photonic crystals (PhC) slab resonators. Such platforms have already been studied for more than one decade and have been widely employed in nanophotonics or in solid state quantum optics, due to the tight optical confinement they provide. This suspended resonators also sustain mechanical modes, in particular high-frequency modes strongly coupled to light. The PhD work aims at understanding and implementing optomechanical effects in such intergated platform, in the linear and non-linear regime.
