Near-Field Optics Imaging in Silica Waveguide Using Near-Field Scanning Optical Microscope [PDF]
Japanese Journal of Applied Physics, 2007 We investigated the near-field optics imaging by a numerical method using special spherical chains created in a silica waveguide (SWG) and explored the possibility of how this can be used for near-field scanning optical microscopy (NSOM) applications. There are two types of spherical nanochain; type A includes nano-dielectric spheres connected closely,

Offset-apertured near-field scanning optical microscope probes
Optics Express, 2007 Near-field scanning optical microscope (NSOM) probe designs consisting of a subwavelength aperture offset of either a metallic or metal-coated dielectric cantilevered tip are investigated using finite-difference time-domain calculations. The offset aperture and metal-coated dielectric tip couple surface plasmons that illuminate the tip apex, which ...

Quick identification of ABC trilayer graphene at nanoscale resolution via a near-field optical route
Materials Futures, 2023 ABC-stacked trilayer graphene has exhibited a variety of correlated phenomena owing to its relatively flat bands and gate-tunable bandgap. However, convenient methods are still lacking for identifying ABC graphene with nanometer-scale resolution. Here we
