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…
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…
