Abstract
According to one aspect, an optical transceiver includes a substrate and a laser fixed to a first surface of the substrate, the laser generating output light for transmission along a transmission axis into a region. An optical detection element is fixed to a second surface of the substrate opposite the first surface, the optical detection element receiving input light reflected from the region along a reception axis through an opening in the substrate between the first and second surfaces of the substrate, the transmission axis and the reception axis being substantially parallel.
