While shaping of the electromagnetic fields around nanostructures is widely studied, the influence of the field inside the nanostructures is often overlooked. Here, Wolf et al. control the spatial distribution of third-harmonic emission in a plasmoni

The plasmon resonance of a metal nanoparticle increases the optical field amplitude in and around the particle with respect to the incoming wave. In consequence, optical effects that are nonlinear in their field amplitude profit from this increased f

Tailoring not only the linear but also the nonlinear properties of plasmonic structures has been a longstanding idea. The plasmonic dolmen structure with its many degrees of freedom in design has b...

We demonstrate the read-out of the conformational state of photoswitchable molecules, without modifying that state by the read-out process itself. The ring-opening and ring-closing reactions change not only the absorption spectrum of a molecular laye

A new concept for second-harmonic generation (SHG) in an optical nanocircuit is proposed. We demonstrate both theoretically and experimentally that the symmetry of an optical mode alone is sufficient to allow SHG even in centro-symmetric structures m

All nonlinear optics textbooks state that second-harmonic generation requires a non-centro-symmetric crystal structure in bulk. In the last decade, asymmetric nanoparticles of centro-symmetric material have been used to generate second-harmonic. We i

Der senegalesische Historiker Cheikh Anta Diop (1923–1986) ist einer der brillantesten Wissenschaftler und aufregendsten „Querdenker“ Afrikas. Er vertritt in seinen Werken vehement die These, dass die ägyptische Kultur eine schwarzafrikanische

Although shaping of fields around nanostructures is widely studied in plasmonics, the influence of the field inside the nanostructures is often overlooked. The linear field distribution inside the structure taken to the third power causes third-harmo
