Relaxed phase-matching constraints in zero-index waveguides
Justin R. Gagnon, Orad Reshef, Daniel H. G. Espinosa +8
The nonlinear optical response of materials is the foundation upon which applications such as frequency conversion, all-optical signal processing, molecular spectroscopy, and nonli…
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…
An Efficient and Compact Excitation of Surface Plasmons Using a Si Gable Tip
Arnab Dewanjee, M. Z. Alam, J. Stewart Aitchison +1
We propose a novel technique to efficiently excite a surface plasmon polariton (SPP) mode at a gold-glass interface by exploiting the near field excitation of an engineered high in…
