Towards compact phase-matched and waveguided nonlinear optics in atomically layered semiconductors
Xinyi Xu, Chiara Trovatello, Fabian Mooshammer +6
Nonlinear frequency conversion provides essential tools for light generation, photon entanglement, and manipulation. Transition metal dichalcogenides (TMDs) possess huge nonlinear…
Nanoscale Optical Imaging of 2D Semiconductor Stacking Orders by Exciton-Enhanced Second Harmonic Generation
Kaiyuan Yao, Shuai Zhang, Emanuil Yanev +9
Second harmonic generation (SHG) is a nonlinear optical response arising exclusively from broken inversion symmetry in the electric-dipole limit. Recently, SHG has attracted widesp…
Giant nonlinear optical responses from photon avalanching nanoparticles
Changhwan Lee, Emma Xu, Yawei Liu +10
Avalanche phenomena leverage steeply nonlinear dynamics to generate disproportionately high responses from small perturbations and are found in a multitude of events and materials,…
Broadband optical parametric amplification by two-dimensional semiconductors
Chiara Trovatello, Andrea Marini, Xinyi Xu +11
Optical parametric amplification is a second-order nonlinear process whereby an optical signal is amplified by a pump via the generation of an idler field. It is the key ingredient…
