Driven by applications in chemical sensing, biological imaging and material
characterisation, Raman spectroscopies are attracting growing interest from a variety of …

Single-molecule (SM) surface-enhanced Raman spectroscopy (SERS) and tip-enhanced
Raman spectroscopy (TERS) have emerged as analytical techniques for characterizing …

The use of Raman spectroscopy for carbon nanotube applications is presented here as a
tutorial review. After introducing the relevant basic aspects of Raman spectroscopy of …

The birth of terahertz imaging approximately coincides with the birth of the journal Optics
Express. The 20^ th anniversary of the journal is therefore an opportune moment to consider …

Raman spectroscopy can be used to measure the chemical composition of a sample, which
can in turn be used to extract biological information. Many materials have characteristic …

Surface‐enhanced Raman scattering (SERS) has become a mature vibrational
spectroscopic technique during the last decades and the number of applications in the …

This review discusses a relatively new technique for optical nanoimaging at visible
wavelength, known as tip-enhanced Raman spectroscopy (TERS). This technique relies on …

Raman spectroscopy is an integral part of graphene research. It is used to determine the
number and orientation of layers, the quality and types of edge, and the effects of …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Optical antennas are devices that convert freely propagating optical radiation into localized
energy, and vice versa. They enable the control and manipulation of optical fields at the …
