Hybrid Deep Reconstruction for Vignetting-Free Upconversion Imaging through Scattering in ENZ Materials
Hao Zhang, Yang Xu, Wenwen Zhang +10
Optical imaging through turbid or heterogeneous environments (collectively referred to as complex media) is fundamentally challenged by scattering, which scrambles structured spati…

High-fidelity spatial information transfer through dynamic scattering media by an epsilon-near-zero time-gate
Yang Xu, Saumya Choudhary, Long D. Nguyen +7
Transparent conducting oxides (TCO) such as indium-tin-oxide (ITO) exhibit strong optical nonlinearity in the frequency range where their permittivities are near zero. We leverage…

Resonance-free Fabry-Pérot cavity via unrestricted orbital-angular-momentum ladder-up
Shaghayegh Yaraghi, Oussama Mhibik, Murat Yessenov +5
Introducing elements into an optical cavity that modify the transverse spatial field structure can also impact the cavity spectral response. In particular, an intra-cavity spatial…
