Two superimposed gratings act to couple light to surface plasmon modes at a metal-air interface. A surface plasmon standing wave is created by generating two counter propagating plasmon waves. The wavelength and angle of incidence of the light that generates the surface plasmon standing wave can be selected by selecting the grating spacing of the couplers. The standing wave can then be out-coupled via the same gratings. In addition to affecting the transmission and reflection signals of the film the structure also enhances the light coupled into the forward- and the back-scattered direction.
