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.

An optoelectronic module, comprising:
- a micro-optical substrate;
- a beam transmitter, comprising a laser die mounted on the micro-optical substrate and configured to emit at least one laser beam along a beam axis;
- a receiver, comprising 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;
- and
- beam-combining optics, which 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.
A method for producing an optoelectronic module, the method comprising:
- mounting a beam transmitter, comprising a laser die configured to emit at least one laser beam along a beam axis, on a micro-optical substrate;
- mounting a receiver, comprising a detector die configured to sense light received by the module along a collection axis of the receiver, on the micro-optical substrate;
- and
- positioning beam-combining optics with respect to the micro-optical substrate so as to direct the laser beam and the received light so that the beam axis is aligned with the collection axis outside the module.
