An optical package comprises a light source generating light having a first aspect ratio, an anamorphic light guide to receive the light from the light source, a diverter array to receive and divert light from the anamorphic light guide, and a concentrator to collect light received from the diverter array, wherein the concentrator outputs light having a second aspect ratio, the second aspect ratio being greater than the first aspect ratio. An effective height of the output beam is lower than an effective height of the light source.
