A fully automated dual-tip scanning near-field optical microscope for localized optical excitation and detection in the visible and near-infrared
Najmeh Abbasirad, Jonas Berzins, Kenneth Kollin +4
Near-field optical microscopes with two independent tips for simultaneous excitation and detection can be essential tools for studying localized optical phenomena on the subwavelen…
Generation and near-field imaging of Airy surface plasmons
Alexander Minovich, Angela E. Klein, Norik Janunts +3
We demonstrate experimentally the generation and near-field imaging of nondiffracting surface waves - plasmonic Airy beams, propagating on the surface of a gold metal film. The Air…
Doubly resonant optical nanoantenna arrays for polarization resolved measurements of surface-enhanced Raman scattering
J. Petschulat, D. Cialla, N. Janunts +9
We report that rhomb-shaped metal nanoantenna arrays support multiple plasmonic resonances, making them favorable bio-sensing substrates. Besides the two localized plasmonic dipole…
