Abstract
Optical apparatus includes a semiconductor substrate and an edge-emitting radiation source, mounted on a surface of the substrate so as to emit optical radiation along an axis that is parallel to the surface. A reflector is fixed to the substrate in a location on the axis and is configured to reflect the optical radiation in a direction that is angled away from the surface. One or more optical elements are mounted on the substrate so as to receive and transmit the optical radiation reflected by the reflector.
Claims20
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 is configured to reflect the optical radiation emitted by all of the plurality of the radiation sources in a direction that is angled away from the surface;
- 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.
An imaging system, comprising:
- an illumination assembly, which is configured to project a pattern of optical radiation onto an object, and which comprises:
- 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 is configured to reflect the optical radiation emitted by all of the plurality of the radiation sources in a direction that is angled away from the surface;
- 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 toward the object;
- an imaging assembly, which is configured to capture an image of the pattern on the object;
- and
- a processor, which is configured to process the image so as to generate a depth map of the object.
A method for producing a photonics module, comprising:
- mounting a plurality of edge-emitting radiation together on a surface of a semiconductor substrate so that the source emits optical radiation along respective axes that are parallel to the surface;
- fixing a reflector to the substrate in a location on the axes so as to reflect the optical radiation emitted by all of the plurality of the radiation sources in a direction that is angled away from the surface;
- and
- mounting one or more optical elements on the substrate so as to receive and transmit the optical radiation reflected by the reflector.
