چکیده
|
Time-resolved imaging of the propagation and interference of isolated ultrashort surface plasmon polariton wave packets is demonstrated using two photon photoemission microscopy. the group- and phase velocity of individual wave packets are determined experimentally. using two counter-propagating surface plasmon polariton pulses, the transient formation of a standing surface plasmon polariton wave is imaged in time and space. we demonstrate that using a normal incidence geometry in time-resolved photoemission microscopy provides great advantages for in-situ imaging of surface plasmon polaritons in arbitrary plasmonic structures. a simple 1d wave-simulation is used to confirm the experimental results.
