Nonlinear optics in the electron-hole continuum in 2D semiconductors: two-photon transition, second harmonic generation and valley current injection
Pu Gong, Hongyi Yu, Yong Wang +1
We investigate two-photon transitions to the electron-hole scattering continuum in monolayer transition-metal dichalcogenides, and identify two contributions to this nonlinear opti…

Optical selection rules for excitonic Rydberg series in the massive Dirac cones of hexagonal 2D materials
Pu Gong, Hongyi Yu, Yong Wang +1
We investigate the optical transition selection rules for excitonic Rydberg series formed in massive Dirac cones. The entanglement of the exciton envelop function with the pseudosp…

Electrical Control of Second-Harmonic Generation in a WSe2 Monolayer Transistor
Kyle L. Seyler, John R. Schaibley, Pu Gong +7
Nonlinear optical frequency conversion, in which optical fields interact with a nonlinear medium to produce new field frequencies, is ubiquitous in modern photonic systems. However…
