ABSTRACT:
The invention applies to a laser integrated circuit comprising at least one row of lasers (30) lying between two reflector strips (28). The lasers (18) are electrically connected in parallel. The light emission along the strip will be more uniform if the electrical current is distributed by two "combs" whose "teeth" are parallel to the laser ribbons (18) and interleaved with them. The terminal metallized area (44) for the first comb is deposited at the bottom of a recess (18) and the terminal metallized areas (45) for the second comb are on the surface of the row. Such a device finds particular application to the power supply for laser integrated circuits.
