„Ultrafast modulation of surface plasmon dispersion in metallic bilayers by hot non-equilibrium electrons ”

Katedra Fizyki Magnetyków Wydziału Fizyki UwB

Here we will discuss the results of research carried out within the framework of the OPUS 18 project and future prospects in the field of plasmonics. There will be discussed experimental results obtained during this project that have been published recently. We investigate an indirect manipulation of the surface plasmon dispersion at the remote Au/air interface. The absorption peak of the surface plasmon resonance experiences a shift at the femtosecond timescale, highlighting the role of hot nonequilibrium electrons for ultrafast plasmonics.
