Patent ID: 7653110

Claim:
A semiconductor laser apparatus comprising: a laser device including: a semiconductor substrate, first and second resonators that are formed on the semiconductor substrate, extend in parallel with each other and are electrically separated from each other, and first and second electrodes that are each electrically connected with corresponding one of the first and the second resonators and extend away from each other; and a submount including: third and fourth electrodes that are electrically separated from each other and are each adhered with corresponding one of the first and the second electrodes by a solder member; wherein each of the first and the second electrodes includes: an energizing portion that covers corresponding one of the first and the second resonators, an adhering portion that is disposed separately from the energizing portion, the adhering portion having a height from a surface of the semiconductor substrate larger than that of the energizing portion, and a stress-absorbing portion that is formed in the adhering portion.
