Resumé

Micro- and nano-scale systems with defined active elements acting as local surface plasmons polariton (SPP) sources are crucial for the development of future plasmonic circuits. We demonstrate SPP excitation by fluorescent light from crystalline organic para-hexaphenylene nanofibers deposited on a dielectric/metal surface. We characterize the SPPs using angle-resolved leakage radiation spectroscopy, in the excitation wavelength range 420 – 675 nm, corresponding to the nanofiber photoluminescence band. The nanofiber arrangement’s capability to act as an SPP coupler for coherent as well as non-coherent excitation indicates its prospect for future integrated systems. To support our experimental results, we investigate the proposed geometries by analytical calculations and finite-difference-time-domain (FDTD) modelling. The experimentally obtained angular leakage radiation peak positions can readily be predicted by our analytical calculations. Nevertheless, the experimental results exhibit a distinct asymmetry in the peak intensities. In agreement with our FDTD calculations, we address this asymmetrical SPP excitation to the nanofiber molecular orientation. The proposed structure’s high flexibility, the ease of selective positioning of organic nanofibers, together with the gained insight into its photon-SPP coupling mechanism show great promise towards future local SPP excitation-based integrated devices.
