To What Extent Can Space Be Compressed? Bandwidth Limits of Spaceplates
Kunal Shastri, Orad Reshef, Robert W. Boyd +2
Spaceplates are novel flat-optic devices that implement the optical response of a free-space volume over a smaller length, effectively "compressing space" for light propagation. To…
Enhanced Nonlinear Optical Responses of Layered Epsilon-Near-Zero Metamaterials at Visible Frequencies
Sisira Suresh, Orad Reshef, M. Zahirul Alam +3
Optical materials with vanishing dielectric permittivity, known as epsilon-near-zero (ENZ) materials, have been shown to possess enhanced nonlinear optical responses in their ENZ r…
On modifications of fundamental radiative processes in near-zero-index media of various dimensions
Lobet Michaël, Iñigo Liberal, Erik N. Knall +5
Spontaneous emission, stimulated emission and absorption are the three fundamental radiative processes describing light-matter interactions. Here, we theoretically study the behavi…
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…
Multi-resonant high-Q plasmonic metasurfaces
Orad Reshef, Md Saad-Bin-Alam, Mikko J. Huttunen +5
Resonant metasurfaces are devices composed of nanostructured sub-wavelength scatterers that generate narrow optical resonances, enabling applications in filtering, nonlinear optics…
