Surface plasmons in the Young slit doublet experiment

Abstract : We present an in-depth analysis of Young's slit experiment when solely a single slit of the doublet is illuminated by a focused laser beam at visible and thermal infrared wavelengths. In line with the recent results obtained by Kuzmin et al.. [Opt. Lett. 32, 445 (2007)], even if only a single slit is illuminated by a focused beam, we show that the far-field pattern exhibits sinusoidal Young's fringes. Thanks to fully vectorial electromagnetic computations and to a simple model, we provide a comprehensive discussion of the nature of surface waves at work in the experiment.
