Semiconductor laser module and optical module |
摘要 |
The present invention provides a semiconductor laser module in which a coupling efficiency does not easily vary even though a displacement amount varies by the effect of welding. The semiconductor laser module comprises: a semiconductor laser element 2 for emitting a laser light whose cross-sectional shape at an emission end face is elliptical; an optical fiber 3 arranged to receive the laser light from the semiconductor laser element 2; a package 4 for housing the semiconductor laser element 2 and the optical fiber 3; a first fastening means 117 for fastening the optical fiber 3 to the package 4; and a second fastening means 7 for fastening the semiconductor laser element 2 to the package 4, wherein the semiconductor laser element 2 and the optical fiber 3 are fastened such that a minor axis of the elliptical shape of the laser light becomes parallel to a line connecting both ends of the optical fiber 3, said both ends being restricted by the first fastening means 117. |
