Heavily doped semiconductors have emerged as tunable low-loss plasmonic materials at
midinfrared frequencies. In this article we investigate nonlinear optical phenomena …

The interaction of light with metallic nanostructures is increasingly attracting interest
because of numerous potential applications. Sub-wavelength metallic structures, when …

We propose surface modulation of the equilibrium charge density as a technique to control
and enhance, via an external static potential, the free electron nonlinear response of heavily …

We develop a methodology to incorporate nonlocal optical response of the free electron gas
due to quantum-interaction effects in metal components of periodic two-dimensional …

Surface-enhanced infrared absorption (SEIRA) spectroscopy is a powerful technique for a
label-free identification of molecular species. The low infrared absorption cross sections of …

We investigate nonlocal electrodynamics based on the generalized hydrodynamic approach
including electron diffusion in holey gold films, showing extraordinary optical transmission …

Recent experiments with film-coupled nanoparticles suggest that the impact of spatial
dispersion is enhanced in plasmonic structures where high wave-vector guided modes are …

We propose and demonstrate a new kind of resonant absorber via introducing the nano-slit
into a photonic film. The combination of the nano-slit cavity and the photonic waveguide …

Recent experiments have shown that spatial dispersion may have a conspicuous impact on
the response of plasmonic structures. This suggests that in some cases, the Drude model …

With the self-consistent mean-field method in the framework of full-wave nonlocal scattering
theory, we theoretically investigate the optical bistability in a nonlocal metallic nanocylinder …
