Infrared up-conversion imaging in nonlinear metasurfaces
Rocio Camacho-Morales, Davide Rocco, Lei Xu +15
Infrared imaging is a crucial technique in a multitude of applications, including night vision, autonomous vehicles navigation, optical tomography, and food quality control. Conven…
Planar narrow-band-pass filter based on Si resonant metasurface
Ze Zheng, Andrei Komar, Khosro Zangeneh Kamali +6
Optically resonant dielectric metasurfaces offer unique capability to fully control the wavefront, polarisation, intensity or spectral content of light based on the excitation and…
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…
Pushing the Limit of High-Q Mode of a Single Subwavelength Dielectric Nanocavity
Lujun Huang, Lei Xu, Mohsen Rahmani +2
High index dielectric nanostructure supports different types of resonant modes. However, it is very challenging to achieve high-Q factor in a single subwavelength dielectric nanore…
Quantum metasurface for multi-photon interference and state reconstruction
Kai Wang, James G. Titchener, Sergey S. Kruk +9
Metasurfaces based on resonant nanophotonic structures have enabled novel types of flat-optics devices often outperforming the capabilities of bulk components, yet these advances r…
High Visibility Two-photon Interference with Classical Light
Peilong Hong, Lei Xu, Zhaohui Zhai +1
Two-photon interference with independent classical sources, in which superposition of two indistinguishable two-photon paths plays a key role, is of limited visibility of interfere…
