Paper Abstract

The ultrafast dynamics of surface electromagnetic waves photogenerated on the surfaces of an Al film perforated with 2D subwavelength hole array was studied by the pump-probe correlation spectroscopy. The time-resolved differential transmission exhibits a fast rise on subpicosecond time scale followed by a plateau with subsequent slow decay. This dynamics is accompanied by a blue shift in transient spectra of the anomalous transmision band. A theoretical model is developed that explains both time-resolved and spectrally-resolved data.
