Scaling native entanglement generation in layered semiconductors with quasi-phase matching
Benjamin Braun, Andrea Alessandrini, Josip Bajo +10
Efficient generation of entangled photons typically relies on spontaneous parametric down-conversion (SPDC) in phase-matched macroscopic nonlinear media. However, generating entang…

Hot-electron-injection-induced symmetry breaking in bilayer MoS probed by second-harmonic generation
Zhizi Guan, Zhiwei Peng, David J. Srolovitz +2
Symmetry governs the selection rules of light-matter interactions in crystalline materials, making symmetry manipulation a powerful tool for tuning their optical properties. Here,…

Strain-Enabled Giant Second-Order Susceptibility in Monolayer WSe
Zhizi Guan, Yunkun Xu, Junwen Li +3
Monolayer WSe (ML WSe) exhibits a high second-harmonic generation (SHG) efficiency under single 1-photon (1-p) or 2-photon (2-p) resonant excitation conditions due to enhan…
