Femtosecond laser written waveguides in sapphire for visible light delivery
Sarah Winkler, Joachim R. Krenn, Jakob Wahl +8
A promising solution for scalable integrated optics of trapped-ion quantum processors are curved waveguides guiding visible light within sapphire bulk material. To the best of our…
Transient absorption microscopy setup with multi-ten-kilohertz shot-to-shot subtraction and discrete Fourier analysis
Robert Schwarzl, Pascal Heim, Manuela Schiek +4
Recording of transient absorption microscopy images requires fast detection of minute optical density changes, which is typically achieved with high-repetition-rate laser sources a…
Fluorescence coupling to plasmonic nanoparticles
Gernot Schaffernak, Christian Gruber, Joachim R. Krenn +4
The combination of single photon emitters (quantum dots) and tailored metal nanoparticles with defined size and shape allows a detailed study of the interaction between light and m…
Gap plasmonics of silver nanocube dimers
Dario Knebl, Anton Hörl, Andreas Trügler +4
We theoretically investigate gap plasmons for two silver nanocubes coupled through a molecular tunnel junction. In absence of tunneling, the red-shift of the bonding mode saturates…
Influence of surface roughness on the optical properties of plasmonic nanoparticles
Andreas Truegler, Jean-Claude Tinguely, Joachim R. Krenn +2
For plasmonic nanoparticles, we investigate the influence of surface roughness inherent to top-down fabrication on the optical properties, and find that it has a surprisingly small…
Analysis of damping-induced phase flips of plasmonic nanowire modes
Andreas Hohenau, Primoz Kusar, Christian Gruber +1
We launch surface plasmons from one end of a silver nanowire by asymmetric illumination with white light and use plasmon-to-light scattering at the nanowire ends to probe spectrosc…
