Abstract:
1. A semiconductor laser module, comprising: a semiconductor laser element; a frame for storing said semiconductor laser element therein; an optical fiber fixing portion being connected to said frame; and a flange being connected to said frame, and having a fixing portion for fixing said frame on a substrate, wherein said flange has a narrow width region between a fixing region, including a fixing portion with said substrate therein, and said frame, and said narrow width region is narrower than width of said fixing region; and wherein: said frame has a polygonal shape, said flange has a first flange connecting to a first main side of said frame and a second flange connecting to a second main side of said frame opposing to said first main side thereof, said first flange is provided in a first region on said first main side, which is divided by an elongated line of a line connecting a portion where said semiconductor laser element is disposed and a portion where an optical fiber of said optical fiber fixing portion is disposed, while no flange is provided in a second region located on a reverse side of said first region, and no flange is provided in a third region located on the second main side of said frame on a side of said first region, opposing to said first main side, while said second flange is provided in a fourth region located on a side of said second region.
