Overview of project B06
Relaxation Pathways for Collective Electronic Excitations
In project B06, the phase-fronts of femtosecond surface plasmon polariton (SPP) pulses are controlled on a sub-wavelength scale by using structured grating couplers. This provides the opportunity to create tailored SPP pulses which induce field strengths and polarizations at the surface that are not achievable with optical methods. The figure illustrates how the project uses Archimedean spirals on Au(111) platelets [1] to create an SPP focus [2, 3]. It is important to note that after SPP excitation the phase fronts propagate to the center of the spiral, and that the exciting femtosecond laser pulses are not present any more when the SPP focus is formed. This spatiotemporal separation allows to investigate the SPP focus in the absence of light, which constitutes a unique experimental situation. The aim of project B06 is to investigate the coupling of SPPs to the electron system in the plasmonic strong-field regime, and to investigate the related (plasmo)emission [4] of electrons with pump-probe photoemission electron microscopy (PEEM). In a normal-incidence geometry for the laser-pulses [5], this method allows imaging the propagation of SPPs with sub-wavelength resolution on a femtosecond time-scale [6]. Furthermore, the electrons emitted from the focus can not only be analyzed with respect to their in spatial distribution, but also their momentum and/or energy-distribution is accessible to the experiment. Project B06 collaborates closely with Project A04, where field-enhancement effects in plasmonic particle-dimers are of interest [7].
Figure: (top) Au (111) platelet with a grating coupler in the shape of an Archimedean spiral, structured using focused ion beams. (bottom left) Design of the grating coupler. If the shown spiral is excited with circularly polarized light results in circular SPP phase-fronts and a SPP focus in the center oft he spiral. (bottom right) PEEM image of the SPP phase fronts and the resulting focus. The work-function of the sample has been lowered by Cs to make the phase-fronts visible.
