Abstract:
1. Optical apparatus, comprising: a semiconductor substrate; a plurality of edge-emitting radiation sources which are mounted together on a surface of the substrate so as to emit respective beams of optical radiation along respective axes that are parallel to the surface; a reflector, which is fixed to the substrate in a location on the axes and which comprises multiple adjacent flat surfaces, wherein each flat surface extends from the substrate to the top of the reflector and is configured to reflect the optical radiation emitted by a respective radiation source among the plurality of the radiation sources at a different, respective angle so that all of the beams are deflected in a direction that is angled away from the surface while imparting a desired convergence or divergence to the optical radiation; and one or more optical elements, which are mounted on the substrate so as to receive and transmit the optical radiation reflected by the reflector.
