Enhanced nonlinear refractive index in epsilon-near-zero materials
L. Caspani, R. P. M. Kaipurath, M. Clerici +9
New propagation regimes for light arise from the ability to tune the dielectric permittivity to extremely low values. Here we demonstrate a universal approach based on the low line…

Optically induced metal-to-dielectric transition in Epsilon-Near-Zero metamaterials
R. M. Kaipurath, M. Pietrzyk, L. Caspani +6
Epsilon-Near-Zero materials exhibit a transition in the real part of the dielectric permittivity from positive to negative value as a function of wavelength. Here we study metal-di…
