Surface Plasmon Polariton Mach-Zehnder Interferometer and Oscillation Fringes

摘要

We present a quantitative experimental analysis of a surface plasmonpolariton (SPP) interferometer relying on elliptical Bragg mirrors. By using aleakage radiation microscope we observe oscillation fringes with unitvisibility at the two interferometer exits. We study the properties of the SPPbeam splitter and determine experimentally both the norm and phase of the SPPreflection and transmission coefficients.
