Abstract

In this work, we study the enhanced nonlinear light-matter interaction in hybrid Weyl-semimetal-plasmonic structure by depositing silver nanocubes on a TaAs surface with a silicon nitride spacer thus leveraging the unique ability of plasmonics to squeeze electromagnetic field within a small volume far below the diffraction limit. Pumping the fabricated hybrid structure utilizing a 800-nm fundamental wavelength pulse at 100 fs we achieve second harmonic generation (SHG) at 400 nm with a 300 percent enhancement of SHG signal while the estimated actual plasmonic SHG enhancement is 90-fold.
