Efficient nonlinear optical interactions are essential for many applications in modern
photonics. However, they typically require intense laser sources and long interaction …

The discovery, design and development of materials are critically linked to advances in
many areas of research, and optics is no exception. Recently, the spectral region in which …

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 linear …

Abstract Epsilon‐near‐zero (ENZ) photonics is the study of light–matter interactions in the
presence of structures with near‐zero permittivity and has been emerging as an important …

We report the simultaneous increase of both nonlinear Kerr coefficient n2 and third-order
nonlinear susceptibility χ (3) in aluminum zinc oxide (AZO) attained by pump-probe …
