摘要： PROBLEM TO BE SOLVED: To obtain the optical coupling system with low optical coupling loss by using an optical semiconductor element which has no spot size converting function by filling a space, constituting at least an optical path between optical component, with a solid light-transmissive organic material having a specific refractive index.
SOLUTION: The optical coupling structure is constituted having at least the optical semiconductor device 1, a lens 2, and an optical fiber 3. Then at least the space between those optical components is filled with the solid light- transmissive organic material 4. The optical semiconductor device 1 is, for example, a light emitting semiconductor device or light receiving semiconductor device. As the solid light-transmissive organic material 4, silicone-based resin, epoxy-based resin, etc., is used. The refractive index n1 of the lens 2 and the refractive index n2 of the transparent organic material 4 are so set than n1>n2. Further, n1 is preferably larger than 1.2×n2 so as to display the function of the lens 2 sufficiently.

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor laser module and its assembling method excellent in the assembling, the handling and the mass-productivity and high in the reliability. SOLUTION: A package case 12 of a semiconductor laser module 100 is formed by molding of plastics. The taking out porting of an optical fiber 5 from the side wall of the case 12 is made to a groove shape with a step which distinguishes an optical fiber installing groove 11 having a different width and a depth from an optical fiber covered installing groove 13. The fiber 5 and an optical fiber cover 10 are fixed to the groove sections 11 and 13. Thus, the fiber 5 and the cover 10 are installed at prescribed positions, the fiber 5 is not joined in the tilted or bent state caused by the hardening and shrinking of resin and the setting condition of the fiber 5. Thus, these is no the danger of causing the discontinuity nor the degradation of an optical coupling of the fiber 5.
