Quantitative and Direct Near-Field Analysis of Plasmonic-Induced Transparency and the Observation of a Plasmonic Breathing Mode

We investigated experimentally and numerically in the optical near-field a plasmonic model system similar to a dolmen-type structure for phenomena such as plasmon-induced transparency. Through engineering of coupling strength, structure orientation, and in ...

Tetradymites as Natural Hyperbolic Materials for the Near-Infrared to Visible

Klaus Kern, Pascal Gehring, Moritz Esslinger

Hyperbolic media exhibit unparalleld properties, e.g, as light absorbers in photovoltaics and photonics, as superlenses in far-field imaging, as subwavelength light concentrators in nanolithography, or as novel materials in emission engineering. With the a ...

Background-free imaging of plasmonic structures with cross-polarized apertureless scanning near-field optical microscopy

Klaus Kern, Moritz Esslinger

We present advances in experimental techniques of apertureless scanning near-field optical microscopy (aSNOM). The rational alignment procedure we outline is based upon a phase singularity that occurs while scanning polarizers around the nominal cross-pola ...

Long-Distance Indirect Excitation of Nanoplasmonic Resonances

Klaus Kern, Moritz Esslinger, Alexandre Dmitriev

In nanoscopic systems, size, geometry, and arrangement are the crucial determinants of the light-matter interaction and resulting nanoparticles excitation. At optical frequencies, one of the most prominent examples is the excitation of localized surface pl ...

Near-Field Dynamics of Optical Yagi-Uda Nanoantennas

Klaus Kern, Moritz Esslinger

We present near-field measurements of optical Yagi-Uda nanoantennas that are used in receiving mode. The eigenmode imaging of amplitude and phase by apertureless scanning near-field optical microscopy allows us to investigate the dynamics of the local out- ...
