Semiconductor Laser array device and method of fabricating the device

摘要

An array type semiconductor laser device includes a foldable submount and a plurality of semiconductor lasers each having uppermost and lowermost layers mounted on the submount. The submount is folded into a polygonal shape having sides with a respective semiconductor laser mounted in the polygon on a corresponding side of the polygon. Therefore, it is easy to mount the semiconductor lasers and a light source can be concentrated on a narrow region.
