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 …

During the past few years, the optics and photonics communities have renewed their
attention toward transparent conducting oxides (TCOs), which for over two decades have …

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 …

Nonlinear optics is concerned with the propagation of intense beams of light through a
material system. The optical properties of the medium can be modified by the intense light …

Nonlinear 2D layered crystals provide ideal platforms for applications and fundamental
studies in ultrathin nonlinear optical (NLO) devices. However, the NLO frequency conversion …

Femtosecond nonlinear optical imaging with nanoscale spatial resolution would provide
access to coupled degrees of freedom and ultrafast response functions on the characteristic …

Efficient optical frequency mixing typically must accumulate over large interaction lengths
because nonlinear responses in natural materials are inherently weak. This limits the …

Metallic nanostructures exhibit localized surface plasmons (LSPs), which offer
unprecedented opportunities for advanced photonic materials and devices. Following …

A time-dependent change in the refractive index of a material leads to a change in the
frequency of an optical beam passing through that medium. Here, we experimentally …

Nonlinear optical processes rely on the intrinsically weak interactions between photons
enabled by their coupling with matter. Unfortunately, many applications in nonlinear optics …
