All-Optical Ultrafast Control of Harmonic Generation in 2D Semiconductors

We attain ultrafast tuning of third-harmonic generation in monolayer WS 2 by all-optical switching. By coupling 2D excitons with photons of a strong non-resonant field, the third-harmonic signal was tuned by up to 26 meV.

Abstract

We attain ultrafast tuning of third-harmonic generation in monolayer WS 2 by all-optical switching. By coupling 2D excitons with photons of a strong non-resonant field, the third-harmonic signal was tuned by up to 26 meV.
