Abstract

Researchers show that resonant coupling of light pulses with excitonic transitions affects the optimal time difference between pulses for sum-frequency generation and four-wave mixing in monolayer WSe2. Monolayer semiconductors are an emerging platform for strong nonlinear light-matter interactions that are enhanced by the giant oscillator strength of tightly bound excitons. Little attention has ...
