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…
