英文摘要	The invention provides a semiconductor laser module and an optical transmission system, with which noise caused by light reflected back from a transmission path can be suppressed. The semiconductor laser module, includes a package having a window, a semiconductor laser chip outputting light, a lens that is optically designed such that it couples the light that is output by the semiconductor laser chip into an optical transmission path, an optical isolator that is disposed between the lens and the window, a temperature control mechanism for keeping temperature of these components constant, and a tubular ferrule that is holds and covers the optical transmission path. The semiconductor laser chip, the lens, the optical isolator, and the temperature control mechanism are arranged inside the package. A polarizer is arranged at an end face of the ferrule on the side of the package, such that the polarizer matches a polarization plane of the light that is emitted through the window of the package.
