Epsilon near zero metamaterials for ultra-low power nonlinear applications [PDF]
, 2015 Epsilon-near-zero metamaterial samples, composed of five alternating bi-layers of silica and silver, are fabricated using the electron-beam evaporator. Nonlinear properties of samples are measured using a pulsed Ti:sapphire laser by the z-scan technique.

Fundamentals and applications of spatial dissipative solitons in photonic devices : [Chapter 6] [PDF]
, 2009 We review the properties of optical spatial dissipative solitons (SDS). These are stable, self‐localized optical excitations sitting on a uniform, or quasi‐uniform, background in a dissipative environment like a nonlinear optical cavity.
