Abstract
The present application concerns an optical device for controlling light, the optical device including: a first waveguide for receiving a light beam from an external light source, at least a second waveguide, an optical coupler for coupling a light beam from the first waveguide to the second waveguide, a beam shaping structure with a light emitting area for emitting a light beam, wherein the second waveguide is configured to guide a light beam coupled from the first waveguide to the beam shaping structure, wherein the beam shaping structure is configured to propagate a light beam received from the second waveguide to the light emitting area such that the beam divergence of a light beam emitted from the light emitting area is lower than the beam divergence of the light beam received from the second waveguide.
