Hyperpolarizability of plasmonic meta-atoms in metasurfaces
M. Saad Bin-Alam, Joshua Baxter, Kashif M. Awan +7
Plasmonic metasurfaces are promising as enablers of nanoscale nonlinear optics and flat nonlinear optical components. Nonlinear optical responses of such metasurfaces are determine…
Tunable Four-Wave Mixing in AlGaAs Waveguides of Three Different Geometries
Daniel H. G. Espinosa, Kashif M. Awan, Mfon Odungide +3
The AlGaAs material platform has been intensively used to develop nonlinear photonic devices on-a-chip, thanks to its superior nonlinear optical properties. We propose a new AlGaAs…
Terahertz Nonlinear Optical Response of Water Vapor
Payman Rasekh, Akbar Safari, Murat Yildirim +4
We report on the nonlinear spectroscopy of water vapor at THz frequencies. Atmospheric water vapor has a rich spectrum with several strong resonances at frequencies below 3 THz, fa…
Ultra-high-Q resonances in plasmonic metasurfaces
M. Saad Bin-Alam, Orad Reshef, Yaryna Mamchur +8
Plasmonic nanostructures hold promise for the realization of ultra-thin sub-wavelength devices, reducing power operating thresholds and enabling nonlinear optical functionality in…
