Multi-functional Metasurface: Visibly and RF Transparent, NIR Control and Low Thermal Emissivity
Mahdi Safari, Nazir P. Kherani, George V. Eleftheriades
Rapid advances in metamaterial technology are enabling the engineering of wave-matter interactions heretofore not realized and functionalities with potentially far-reaching implica…
Laser Cooling of Germanium Semiconductor Nanocrystals
Manuchehr Ebrahimi, Wei Sun, Amr S. Helmy +1
Laser cooling of matter through anti-Stokes photoluminescence, where the emitted frequency of light exceeds that of the impinging laser by virtue of absorption of thermal vibration…
Adiabatic Mode Transformation in Width-graded Nano-gratings: Enabling Multiwavelength Light Localization
Moein Shayegannia, Arthur O Montazeri, Katelyn Dixon +3
We delineate the four principal surface plasmon polariton coupling and interaction mechanisms in subwavelength gratings, and demonstrate their significant roles in shaping the opti…
Reactor based XPS and other in-situ studies on the Effect of Substitution of Bismuth for Indium in Defect Laden Indium Oxide Hydroxide BizIn2-zO3-x(OH)y on the Photocatalytic Hydrogenation of Carbon Dioxide
Joel Y. Y Loh, Yufeng Ye, Nazir P. Kherani
The photocatalytic activity of nanostructured In2O3-x(OH)y for the Reverse Water Gas Shift (RWGS) Reaction CO2 + H2 -> CO + H2O can be greatly enhanced by substitution of Bi(III) f…
Dual Plasmonic Modes from In-Situ Silver Nanoparticle Formation via Diffusion at Silver / Dielectric Interfaces
Yufeng Ye, Joel Y. Y. Loh, Andrew Flood +5
Metal-dielectric interfaces of various geometries are fundamental photonic material platforms for surface plasmons. Surface plasmon polaritons and localized surface plasmons are tw…
Asymmetric Metal-dielectric Meta-cylinders and their Potential Applications from Engineering Scattering Patterns to Spatial Optical Signal Processing
Ali Momeni, Mahdi Safari, Ali Abdolali +2
We propose a novel type of bi-anisotropic hybrid metal-dielectric structure comprising dielectric and metallic cylindrical wedges wherein the composite meta-cylinder enables advanc…
Length Scale Dependence of Periodic Textures for Photoabsorption Enhancement in Ultra-thin Silicon Foils and Thick Wafers
K Kumar, A Khalatpour, G Liu +2
In this paper, we simulate a front surface inverted pyramidal grating texture on 2 to 400 micron thick silicon and optimize it to derive maximum photocurrent density from the cell.…
Rainbow-trapping by adiabatic tuning of intragroove plasmon coupling
Arthur O. Montazeri, Yuan S. Fang, Peyman Sarrafi +1
It is shown here that rendering the width of nano-grooves into a tunable parameter presents a new means of light trapping in subwavelength gratings. Particularly, in gratings with…
Electrical, Optical and Structural Properties of Improved Transparent Conductive Oxide TCO Films
Wahid Shams-Kolahi, Nazir P. Kherani
High Frequency (GW) Post Processing of Transparent Conductive Oxide, ITO, leads to a significant improvement of Optical Transmission and Electrical Conduction. This is also true in…
