Abstract:
1. An integrated semiconductor laser device comprising: a first semiconductor laser element including a first emission region and having a projecting portion; and a second semiconductor laser element including a second emission region and having a recess portion, wherein said projecting portion of said first semiconductor laser element is fitted to said recess portion of said second semiconductor laser element, said first semiconductor laser element has an active layer located under said projecting portion; said active layer located under said projecting portion is said first emission region, said first semiconductor laser element further includes a first electrode arranged on the side closer to said second semiconductor laser element for supplying electric power to said first emission region, said second semiconductor laser element further includes a second electrode arranged on the side closer to said first semiconductor laser element for supplying electric power to said second emission region, and an insulating film is arranged at least between said first electrode and said second electrode, said insulating film has an opening in a region other than a region overlapping said projecting portion, and said first electrode is electrically connected with an external device from said second semiconductor laser element side of the integrated semiconductor laser device through said opening of said insulating film.
