Abstract
The disclosure concerns an integrated circuit which forms an electronic power device. This integrated circuit has, supported by a substrate, at least one array of lasers and at least one flat bar of reflectors. The reflectors send back the laser beams, emitted parallel to the substrate, perpendicularly to the substrate. The cleaved faces of the lasers are obtained by the sub-etching of the arrays, then through breaking by ultrasound.
