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…

Nonlinear virtual lens for programmable and multispectral infrared upconversion imaging
Ze Zheng, Olga Sergaeva, Davide Rocco +5
Conventional infrared (IR) imaging techniques depend on IR cameras based on narrow-bandgap semiconductors, which offer limited spectral bandwidth, coupled with a separate lens. Rec…

Multiple Bound States in the Continuum: Towards Intense Terahertz Matter Interaction
Quanlong Yang, Zhibo Yao, Lei Xu +10
Bound states in the continuum (BICs) are an excellent platform enabling highly efficient light-matter interaction in applications for lasing, nonlinear generation, and sensing. How…
