Claim 10:
11. An electronic device, comprising:
a substrate having a laser driver built-in;
a semiconductor laser mounted on one surface of the substrate; and
connection wiring configured to electrically connect the laser driver and the semiconductor laser by a wiring inductance of 0.5 nanohenries or less,
wherein the semiconductor laser and the laser driver overlap one another,
wherein an area of the overlap between the semiconductor laser and the laser driver includes less than half of an area of the semiconductor laser and less than half of an area of the laser driver, and
wherein the connection wiring is a via that extends through the substrate, between the laser driver and the semiconductor laser, and within the area of overlap between the semiconductor laser and the laser driver.
