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…

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…

A nonreciprocal optical resonator with broken time-invariance for arbitrarily high time-bandwidth performance

Ivan Cardea, Davide Grassani, Simon J. Fabbri +6

Most present-day resonant systems, throughout physics and engineering, are characterized by a strict time-reversal symmetry between the rates of energy coupled in and out of the sy…
