Abstract [en]

We propose a tunable unidirectional long-range surface plasmon polaritons (LRSPP) launcher based on subwavelength metallic nanoslits in the visible range. The direction of the generated LRSPPs could be tuned simply by varying the incident angles. The extinction ratio reaches up to 28 dB with a wide angular width of 30 degrees. The influences of the launcher geometry on its performance are investigated in this study as well. The broadband property of the launcher is also demonstrated.
