Abstract

Surface Plasmon Polaritions(SPP) are electromagnetic waves that travel in the interface of a metal and dielectric and are coupled to collective oscillation of free electrons. SPP tomography is an imaging technique that permits the study of the interference features formed at the metal-air interface of a sample due to the superposition of SPP beams, with high fidelity.
We present an experimental study on the formation of SPP standing waves. We demonstrate that SPP tomography in a quantum eraser arrangement permits the detection of photons passing through the dark fringes of the observed interference pattern. We present a comprehensive explanation of how photons could pass undetected across the regions occupied by the dark fringes.
