Abstract: In one aspect, there is provided an apparatus. The apparatus may include a waveguide layer to guide an optical beam, and a lenslet layer, coupled to a surface of the waveguide layer, to focus a portion of the optical beam. The apparatus may further include a first active layer, coupled to another surface of the waveguide layer, to allow the portion of the optical beam to decouple from the waveguide layer by passing through the first active layer in at least one selectable region of the first active layer. The apparatus may further include a redirecting layer, coupled to or proximate to the first active layer, to redirect the portion of the optical beam decoupled from the waveguide towards the lenslet layer.
