Surface Plasmon mediated near-field imaging and optical addressing in nanoscience
A. Drezet, A. Hohenau, J. R. Krenn +2
We present an overview of recent progress in plasmonics. We focus our study on the observation and excitation of surface plasmon polaritons (SPPs) with optical near-field microscop…
Wavelength-scale stationary-wave integrated Fourier-transform spectrometry
Etienne Le Coarer, Sylvain Blaize, Pierre Benech +7
Spectrometry is a general physical-analysis approach for investigating light-matter interactions. However, the complex designs of existing spectrometers render them resistant to si…
Dynamical ultrafast all-optical switching of planar GaAs/AlAs photonic microcavities
Philip J. Harding, Tijmen G. Euser, Yoanna-Reine Nowicki-Bringuier +2
The authors study the ultrafast switching-on and -off of planar GaAs/AlAs microcavities. Up to 0.8% refractive index changes are achieved by optically exciting free carriers at 172…
CdSe-single-nanoparticle based active tips for near-field optical microscopy
N. Chevalier, M. J. Nasse, J . C. Woehl +4
We present a method to realize active optical tips for use in near-field optics that can operate at room temperature. A metal-coated optical tip is covered with a thin polymer laye…
