Simultaneous spatial and temporal control of nanooptical fields
Prof. M. Aeschlimann (Institut fuer Physik, Universitaet Kaiserslautern)

The flexible simultaneous control of temporal and spatial properties of nanooptical fields opens new possibilities to tailor and optimize the light-matter interaction in spectroscopic methods as well as in nanophotonic applications. Based on the combination of polarization pulse shaping and time-resolved photoemission electron microscopy (PEEM) we demonstrate such a control of an electromagnetic excitation in the vicinity of metallic nanostructures. The present status of different control mechanisms of the local near field will be reviewed, and the prospects of open-loop control of particular nanophotonic excitations will be discussed. The existence of long-lived resonances with coherence lifetimes in the order of 100fs of near field hot-spots on deterministically or randomly structured metal surfaces enables new coherent control experiments even at metal surfaces.
