Abstract

We report quantitative measurements of the radiation forces exerted on a micrometer dielectric sphere by a Surface Plasmon Polariton (SPP) excited at a gold/water interface. We separate the contributions of the two constituents of the plasmon wave - the electromagnetic field and the charge-density oscillations - to the total radiation force. Measurements performed with a Photonic Force Microscope (PFM) show an enhanced attraction to the surface compared to a conventional evanescent wave at the dielectric interface (10² enhancement factor).
