Nonlinear Optical Microscopy of Semiconductor Metal-Nanocavities
Riya Varghese, Shambhavee Annurakshita, Yaraslau Tamashevich +13
We use second and third harmonic generation microscopy to investigate the nonlinear optical response of GaAs nanocavities embedded in a gold film and compare them to bare GaAs nano…

Structured Light-Matter Interaction: Twisted Photons in Graphene
Yaraslau Tamashevich, Marco Ornigotti
In this work we present a numerical framework for studying the interaction of structured electromagnetic fields, i.e., light pulses carrying orbital angular momentum (OAM), interac…

Field theory description of the non-perturbative optical nonlinearity of epsilon-near-zero media
Yaraslau Tamashevich, Tornike Shubitidze, Luca Dal Negro +1
In this paper we introduce a fully non-perturbative approach for the description of the optical nonlinearity of epsilon-near-zero (ENZ) media. In particular, based on the rigorous…
