Surface plasmon propagation in an elliptical corral
arXiv:1002.1588 · doi:10.1063/1.1870107
Abstract
We report the experimental realization of an elliptical Bragg reflector acting as an interferometer for propagating surface plasmon sSPd waves. We investigate SP interferometry in this device using a leakage radiation microscope and we compare our observations with a theoretical model for SP propagation. Strong SP focalization as a function of laser polarization orientation is observed and justified.
