ABSTRACT:
Laser elements are arranged in two dimensions in an elongated region which is longer in the horizontal direction than in the vertical direction, wherein n laser elements are arranged in the horizontal direction, while m laser elements in the vertical direction, where n>m. The anode wiring extends to a direction which is inclined to the horizontal direction and the cathode wiring extends to another direction inclined to the horizontal direction, thereby the anode wiring and the cathode wiring crossing with each other. The anodes of m laser elements in maximum arranged in the direction of the anode wiring are connected to an anode wire, while the cathodes of m laser elements in maximum arranged in the cathode wiring are connected to a cathode wire. Accordingly, even if the array is longer in the horizontal direction and a large number of laser elements are aligned in the horizontal direction, the wiring resistance and electrostatic capacitance of each wire forming the oblique matrix wiring can be small and the operation delay of the laser element can also be small.
