Abstract
A light coupling element including a plurality of waveguide attachment features and a light redirecting member is described. Each attachment feature has an entrance end opposite a terminal end. The entrance ends are arranged at a pitch Pe. The light redirecting member is disposed closer to the terminal ends, and farther from the entrance ends, and includes an input surface, a reflecting side and an exit surface. When a waveguide is attached at each attachment feature, a central light ray emitted by each waveguide enters the light redirecting member through the input surface, is redirected by the reflecting side and exits the light redirecting member at the exit surface, the central light ray intersecting the exit surface at an exit point, each attachment feature corresponding to a different exit point at the exit surface. The exits points are arranged at a pitch Px not equal to Pe.
