Zusammenfassung:
We investigate the optical nonlinear effects of a
long-range surface plasmon polariton mode propagating on
a thin gold film. These effects may play a key role in the
design of future nanophotonic circuits as they allow for
the realization of active plasmonic elements. We demonstrate
a significant enhancement of the transmission on a timescale below a millisecond as well as a phase shift exceeding 2π already for modest peak powers of 150 mW. On the contrary, slow effects suppress the transmission on a
millisecond timescale.
