Since the first report on the far-field optical detection of single metal nanoparticles in the late
1990s, the field has rapidly developed and new methods and concepts have been …

That is nothing new of course. Without knowing any physics, medieval artists produced
stained glass windows that we still admire today after being exposed to sunlight for …

We investigate graphene and graphene layers on different substrates by monochromatic
and white-light confocal Rayleigh scattering microscopy. The image contrast depends …

Highly confined vectorial electromagnetic field distributions are an excellent tool for detailed
studies in nano-optics, such as nonlinear microscopy, advanced fluorescence imaging, or …

Nanoparticles are actively exploited as biological imaging probes. Of particular interest are
gold nanoparticles because of their nonblinking and nonbleaching absorption and …

We introduce an imaging technique based on second-harmonic generation with cylindrical
vector beams that is extremely sensitive to three-dimensional orientation and nanoscale …

The complete three-dimensional orientations of single gold nanorods (AuNR) were
successfully resolved by using a standard optical darkfield microscope through deciphering …

The tip-sample distance (z) dependence of tip-enhanced Raman scattering (TERS) has
been investigated. The intensities of both, the Raman lines and the broad TERS …

Control of the polarization distribution of light allows tailoring the electromagnetic response
of plasmonic particles. By rigorously extending the generalized multiparticle Mie theory, we …

Microscopic techniques based on nonlinear optical processes provide alternative ways to
visualize natural and artificial nanoscopic systems with minimum disturbance. In such …
