PURPOSE:To obtain a laser diode module which is easy to assemble by disposing a ferrule in the groove on the side wall of a package, passing an optical fiber into the ferrule and disposing the ferrule into the package by means of a mounting pipe and a saddle so that the end of the fiber is disposed to face a laser chip in proximity thereto. CONSTITUTION:The front end of the optical fiber 17 is worked to a lens 18 and the mounting pipe 19 is inserted onto the fiber and is soldered thereto. The saddle unit 24 on which a saddle 21 is put is disposed into the package 11 so that the lens 18 faces the laser diode chip 12. The ferrule 25 is mounted to the other end of the fiber 17 and is welded to the notch 23 on the side wall of the package facing the chip 12. A cap is put on top of the package and the notch 23 and is hermetically sealed by soldering. The small-sized and easy- to-assemble laser diode module 27 is formed by this constitution. |
