We report on a method to generate a stationary interference pattern from two independent optical sources, each illuminating a single slit in Young’s interference experiment. The pattern arises as a result of the action of surface plasmons traveling between subwavelength slits milled in a metal film. The visibility of the interference pattern can be manipulated by tuning the wavelength of one of the optical sources.
