Resonant dielectric nanoparticles made of materials with large positive dielectric permittivity,
such as Si, GaP, GaAs, have become a powerful platform for modern light science, enabling …

Optical microscopy, the simultaneous acquisition of spectroscopic and spatial information
using light, forms the basis of many natural sciences. In this chapter, we review a novel …

Metallic nanostructures possess plasmonic resonances that spatially confine light on the
nanometre scale. In the ultimate limit of a single nanostructure, the electromagnetic field can …

Plasmonic high-harmonic generation (HHG) drew attention as a means of producing
coherent extreme ultraviolet (EUV) radiation by taking advantage of field enhancement …

Optical detection of single molecules mostly relies on their fluorescence because of the high
contrast of this technique against the background. Since their invention in the early 1990s …

Ultrafast two-dimensional infrared spectroscopy (2D IR) has been advanced in recent years
toward measuring signals from only a monolayer of sample molecules at solid–liquid and …

Tip-enhanced near-field optical microscopy (TENOM) is a scanning probe technique
capable of providing a broad range of spectroscopic information on single objects and …

Recent progress in nanofabrication has led to tremendous technological developments for
devices that rely on the interaction of light with nanostructured matter. Nanophotonics has …

As a typical membrane matrix with attractive flexibility, paper has exhibited great feasibility to
serve as surface-enhanced Raman scattering (SERS) substrate in the environmental …

Surface enhanced Raman scattering (SERS) is an optical spectroscopy technique with
single molecule sensitivity and chemical specificity. The electromagnetic enhancement …
