Anisotropic Generation and Detection of Surface Plasmon Polaritons Using Near-Field Apertured Probes

open access: yesIEEE Photonics Journal, 2023
Most recent studies centered on light-matter interactions at the nanoscale rely on near-field microscopy. Despite this, few works have been reported to date regarding the anisotropic generation of surface plasmons polaritons on metallic surfaces.

Near-field scanning optical microscopy of photonic crystal nanocavities [PDF]

open access: yes, 2003
Near-field scanning optical microscopy was used to observe high-resolution images of confined modes and photonic bands of planar photonic crystal (PPC) nanocavities fabricated in active InGaAsP material. We have observed the smallest optical cavity modes,

Near-Field Microwave Microscopy for 3D Surface Assessment of Manufactured Structures

open access: yesIEEE Journal of Microwaves, 2023
Using near-field scanning microwave microscopy as a contact and non-contacting investigative tool for 3D surface metrology with three differing measurement modes, it has been possible to analyse structures that may be difficult for existing metrology ...

Waveguide mode imaging and dispersion analysis with terahertz near-field microscopy [PDF]

open access: yes, 2009
Propagation of terahertz waves in hollow metallic waveguides depends on the waveguide mode. Near-field scanning probe terahertz microscopy is applied to identify the mode structure and composition in dielectric-lined hollow metallic waveguides.

Near-field scanning optical microscopy nanoprobes

open access: yesNanotechnology Reviews, 2012
Near-field scanning optical microscopy (NSOM) is a powerful method for the optical imaging of surfaces with a resolution down to the nanometer scale. By focusing an external electromagnetic field to the subwavelength aperture or apex of a sharp tip, the ...

High-Resolution Near-Field Raman Microscopy of Single-Walled Carbon Nanotubes [PDF]

open access: yes, 2003
We present near-field Raman spectroscopy and imaging of single isolated single-walled carbon nanotubes with a spatial resolution of ≈25  nm. The near-field origin of the image contrast is confirmed by the measured dependence of the Raman scattering ...

Mapping three-dimensional near-field responses with reconstruction scattering-type scanning near-field optical microscopy

open access: yesAIP Advances, 2017
Scattering-type scanning near-field optical microscopy (s-SNOM) enables mapping of nanoscale field distributions in two dimensions. However, the standard s-SNOM technique lacks direct resolving ability along the vertical direction, therefore unable to ...
