Interference Induced Complex Nonlinearities in Metal-ITO Metasurfaces
Christopher E. Stevens, Matthew Klein, Ashley Luo +6
We combine modeling and experiments to investigate second- and third-harmonic generation (SHG/THG) in metal-indium tin oxide (ITO) metasurfaces. Linear optics at normal incidence s…
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…
Electrically reconfigurable nonvolatile flatband absorbers in the mid-infrared with wide spectral tuning range
Romil Audhkhasi, Virat Tara, Matthew Klein +5
While recent advances in reconfigurable photonics have provided new avenues for manipulating light on the subwavelength scale, on-demand control of infrared absorption remains elus…
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…
Gate-Tunable Optical Anisotropy in Wafer-Scale, Aligned Carbon-Nanotube Films
Jason Lynch, Evan Smith, Adam Alfieri +10
Telecommunications and polarimetry both require the active control of the polarization of light, Currently, this is done by combining intrinsically anisotropic materials with tunab…
