An epsilon-near-zero-based nonlinear platform for ultrafast re-writable holography
M. Zahirul Alam, Robert Fickler, Yiyu Zhou +3
We re-examine real-time holography for all-optical structuring of light and optical computation using a contemporary material: a subwavelength-thick, spatially unstructured film of…

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…
