Abstract
Recent theoretical and experimental studies indicated that at certain conditions surface plasmon oscillations (SPOs) may show non-classical properties. In this study we present the results of our measurements on spatial distribution and photon statistics of the light emitted by surface plasmon oscillations. Both visible and near infrared lasers have been used for generation of surface plasmons. The experiments were performed in the Kretschmann geometry using both gold and silver layers at several laser pumping powers. We used different type of photo detectors in the photon counting regime to measure the statistical properties of the light generated by surface plasmons. The photon statistics have been measured by different methods. Time interval statistics, photon-number distribution and correlation function of the generated light were determined and compared to those of the exciting laser. Correlations between statistical properties of the light emitted by decaying surface plasmons and the exciting laser source have been studied.
