On-chip low-loss all-optical MoSe modulator
Mohammed Alaloul, Jacob B Khurgin, Ibrahim Al-Ani +4
Monolayer transition metal dichalcogenides (TMDCs), like MoS, MoSe, WS, and WSe, feature direct bandgaps, strong spin-orbit coupling, and exciton-polariton interact…
Boosted second-harmonic generation in the LiNbO metasurface governed by high-Q guided resonances and bound states in the continuum
Ze Zheng, Lei Xu, Lujun Huang +4
To date, second-harmonic generation (SHG) at nanoscale has been concentrated on employing high-refractive-index nanostructures, owing to the strong field confinement at deep subwav…
Enhanced Light-Matter Interaction in Two-Dimensional Transition Metal Dichalcogenides
Lujun Huang, Alex Krasnok, Andrea Alu +3
Two dimensional (2D) transition metal dichalcogenide (TMDC) materials, such as MoS2, WS2, MoSe2, and WSe2, have received extensive attention in the past decade due to their extraor…
Broadband Control on Scattering Events with Interferometric Coherent Waves
Jeng Yi Lee, Lujun Huang, Lei Xu +2
We propose a universal strategy to realize a broadband control on arbitrary scatterers, through multiple coherent beams. By engineering the phases and amplitudes of incident beams,…
Multipolar second-harmonic generation from high- quasi-BIC states in nanoresonators
Irina I. Volkovskaya, Lei Xu, Lujun Huang +2
Multimode interference and multipolar interplay govern functionalities of optical nanoresonators and nonlinear nanoantennas. Recently, excitation of the high-quality supercavity mo…
Enhanced Light-Matter Interactions in Dielectric Nanostructures via Machine Learning Approach
Lei Xu, Mohsen Rahmani, Yixuan Ma +9
A key concept underlying the specific functionalities of metasurfaces, i.e. arrays of subwavelength nanoparticles, is the use of constituent components to shape the wavefront of th…
