Couplings between Photons and Ensemble of Emitters in a High- Cavity at Mesoscopic Excitation Levels
Chenjiang Qian, Viviana Villafañe, Pedro Soubelet +2
We investigate the coupling between an ensemble of individual emitters and multiple photons in a high- cavity at the mesoscopic excitation level. The master equation theory is u…
Probing Dark Excitons in Monolayer MoS by NonLinear Two-Photon Spectroscopy
Chenjiang Qian, Viviana Villafañe, Pedro Soubelet +3
We report a new dark exciton in monolayer MoS using second harmonic generation spectroscopy. Hereby, the spectrally dependent second harmonic generation intensity splits into t…
Thickness Insensitive Nanocavities for 2D Heterostructures using Photonic Molecules
Peirui Ji, Chenjiang Qian, Jonathan J. Finley +1
Two-dimensional (2D) heterostructures integrated into nanophotonic cavities have emerged as a promising approach towards novel photonic and opto-electronic devices. However, the th…
Strain control of exciton and trion spin-valley dynamics in monolayer transition metal dichalcogenides
Zhao An, Pedro Soubelet, Yaroslav Zhumagulov +10
The electron-hole exchange interaction is a fundamental mechanism that drives valley depolarization via intervalley exciton hopping in semiconductor multi-valley systems. Here, we…
Lasing of Moiré Trapped MoSe/WSe Interlayer Excitons Coupled to a Nanocavity
Chenjiang Qian, Mirco Troue, Johannes Figueiredo +8
We report lasing of moiré trapped interlayer excitons (IXs) by integrating a pristine hBN-encapsulated MoSe/WSe heterobilayer into a high- () nanophotonic cavity.…
Emitter-Optomechanical Interaction in Ultra-High-Q hBN Nanocavities
Chenjiang Qian, Viviana Villafañe, Martin Schalk +6
Integrating quantum emitters into nanocavities which simultaneously couple to the photonic and mechanical modes is critical for interfacing electron spins, photons and phonons in t…
