Abstract: An opto-electronic device includes a semiconductor substrate having a planar surface. An emitter is formed on the substrate and configured to emit a beam of light away from the planar surface. A reflective layer is formed on the planar surface adjacent to the emitter. A transparent layer is formed over the planar surface and has a curved outer surface including a first segment positioned vertically over the emitter and configured to internally reflect the emitted beam of light toward the reflective layer, and a second segment positioned and configured to collimate and transmit the beam reflected from the reflective layer.

Abstract: An optical device includes a light source, which is configured to emit a beam of light at a given wavelength, and at least one scanning mirror configured to scan the beam across a target scene. Light collection optics include a collection optic positioned to receive the light from the scene that is reflected from the at least one scanning mirror and to focus the collected light onto a focal plane, and a non-imaging optical element including a solid piece of a material that is transparent at the given wavelength, having a front surface positioned at the focal plane of the collection lens and a rear surface through which the guided light is emitted from the material in proximity to a sensor, so that the collected light is guided through the material and spread over the detection area of the sensor.
