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.
