Contrast-Enhanced Nonlinear Imaging with Moiré Flatband Superlattices
Amin Zamani, Lihang Feng, Jianji Liu +5
Nonlinear metasurfaces offer a compact platform for infrared-to-visible conversion and imaging, yet resonant enhancement is often accompanied by restricted angular acceptance, limi…
Animated Ultraviolet Holography via Programmable Nonlinear Phase Transfer
Ze Zheng, Olga Sergaeva, Davide Rocco +8
Dynamic and programmable control of ultraviolet (UV) light remains challenging because of conventional high material absorption and the limited functionality of optics such as lens…
Linear and nonlinear optical tuning with SbS-based metasurfaces
Amin Zamani, Meibao Qin, Gabriel Sanderson +11
Here, we experimentally demonstrate the unique properties of SbS metasurfaces on monolithic and hybridised SbS-Si platforms. Their advantages are particularly prono…
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…
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…
