Abstract

An optoelectronic module includes a micro-optical substrate and a beam transmitter, including a laser die mounted on the micro-optical substrate and configured to emit at least one laser beam along a beam axis. A receiver includes a detector die mounted on the micro-optical substrate and configured to sense light received by the module along a collection axis of the receiver. Beam-combining optics are configured to direct the laser beam and the received light so that the beam axis is aligned with the collection axis outside the module.
