Abstract
A transceiver having a light source die, a photodetector die and a substrate is disclosed. The substrate has a first well in which the light source die is mounted and a second well in which the photodetector die is mounted. The substrate has a reflective surface which blocks light leaving the light source from reaching the photodetector unless the light is reflected by an object external to the transceiver. The reflecting surface of the second well in the substrate is shaped to concentrate light received from outside the transceiver onto the photodetector, and in one aspect of the invention it comprises a non-imaging optical element. The light source is powered by applying a potential between first and second contacts on the light source die. A signal is generated between first and second contacts on the photodetector die in response to illumination of the photodetector die.
