Resonances in optical systems are useful for many applications, such as frequency comb generation, optical filtering, and biosensing. However, many of these applications are difficult to implement in optical metasurfaces because traditional approache

Multiresonant metasurfaces could enable many applications in filtering, sensing, and nonlinear optics. However, developing a metasurface with more than one high-quality-factor or high-Q resonance at designated resonant wavelengths is challenging. Her

Hyperpolarizability is a measure of the nonlinear optical characteristics of natural or meta-atoms describing how the atoms become nonlinearly polarized by the induced local-field. However, determining hyperpolarizability in the case of structured pl

We present a design for a plasmonic metasurface based on surface lattice resonances that features multiple pre-defined resonances. The resonance wavelengths are determined using inverse Fourier transforms of the particle positions.

We experimentally demonstrate an ultra-high Q-factor (≈2400) surface lattice resonance in a plasmonic metasurface, that can be a great platform for highly-efficient flat optical applications e.g. biosensors, nanolasers, and metalenses.

Plasmonic metasurfaces are promising as enablers of nanoscale nonlinear optics and flat nonlinear optical components. Nonlinear optical responses of such metasurfaces are determined by the nonlinear optical properties of individual nanostructured pla

We experimentally measure the microscopic 2nd-order nonlinear optical response of plasmonic meta-atoms known as the 1st-order hyperpolarizability. This result is crucial to design nonlinear metasurfaces consisting of plasmonic meta-atoms.
