英文摘要 | The object of the present invention is to provide a semiconductor laser module capable of reducing the burdens for the arrangement of the optical system than the conventional one. The semiconductor laser module comprises: a semiconductor laser 1 for emitting, as a transmitted light, a light with a wavelength within a certain communication wavelength band such as, for example, 3 .mu.m band; a cooling means 2a, 2b for cooling the semiconductor laser 1; a stem 3 and cap 4 composing a package; a coupling lens 5, to which the transmitted light leaving the semiconductor laser 1 enters; an optical fiber 8, with which a coupling lens 5 is connected by fusion on its edge face, for optically coupling the transmitted light via the coupling lens 5 thereby propagating; a lens mount piece 6 for fixing and mounting at least a portion of the coupling lens 5 or optical fiber 8; an optical fiber holder 7 for holding the optical fiber 8; and a mount substrate 9, to which the cooling means 2a, 2b and the lens mount piece 6 are disposed; wherein the coupling lens 5 consists of a first GRIN lens portion with a numerical aperture larger than or equal to that of the numerical aperture NAI of the semiconductor laser 1 multiplied by 4, and a second GRIN lens portion 5b with a numerical aperture similar to that of the SMF 8. |
