Spatiotemporal characterisation of nanofabricated silver plasmonic waveguides using 2P-PEEM — •Kellie Pearce^1,2, Christian Späth¹, Soo Hoon Chew^1,2, Sebastian Nobis¹, Anika Spreen¹, Jürgen Schmidt¹, and Ulf Kleineberg¹ — ¹Department of Physics, Ludwig Maximilian University of Munich, Garching, Germany — ²Max Planck Institute of Quantum Optics, Garching, Germany

We characterise the static and dynamic properties of plasmonic waveguides and nanostructures using two-photon photoemission electron microscopy (2P-PEEM). The influence of the size, shape, and length of nanolithographically fabricated silver arrow-like waveguides on the surface plasmon excitation, propagation and focussing is investigated. In addition, we examine the polarization dependence of hotspots in coupled structures such as silver bow ties and chemically-synthesised gold nanospheres. Characterisation is performed as a first step towards time-resolved measurements using 10kHz few-cycle laser pulses.
