Abstract
According to an aspect of the present inventive concept there is provided a light distribution device comprising a waveguide comprising a light coupling portion for light propagation, and a slab layer comprising a light coupling edge arranged at a boundary of the slab layer, configured for light propagation. The light coupling portion extends alongside and at a distance from the light coupling edge, forming a gap therebetween. The light distribution device is configured to allow light in the waveguide to be coupled into the slab layer across the gap. The slab layer is configured to propagate light coupled into the slab layer such that an interference pattern is formed in the slab layer, and for control of the interference pattern.
