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…
How to organize an online conference
Orad Reshef, Igor Aharonovich, Andrea Armani +4
On January 13th 2020, the inaugural Photonics Online Meetup (POM) brought together more than 1100 researchers to discuss the latest advances in photonics. Or rather, it didn't, bec…
An optic to replace space and its application towards ultra-thin imaging systems
Orad Reshef, Michael P. DelMastro, Katherine K. M. Bearne +4
Centuries of effort to improve imaging has focused on perfecting and combining lenses to obtain better optical performance and new functionalities. The arrival of nanotechnology ha…
