Figure 2: Experimental set-up utilized to measure exotic trajectories of light.

(a) Sketch of the experimental set-up used to measure the far-field interference patterns for the various slit configurations. (b) The seven different slit arrangements used in our study. This drawing is not to scale; in the actual experiment each slit structure was well separated from its neighbors to avoid undesired cross talk. (c) Detail of the structure mounted on the set-up. The refractive index of the immersion oil matches that of the glass substrate creating a symmetric index environment around the gold film.
