ABSTRACT:
A manufacturing apparatus comprises a heating device for heating a semiconductor laser in an optical transmission module package, a temperature sensor for measuring a temperature of the semiconductor laser, an optical power meter for measuring an optical output of the semiconductor laser, a manipulator for holding an optical fiber and positioning an end of the optical fiber to a desired position and a control unit for controlling the heating device and the manipulator. The control unit reads data measured by the temperature sensor and the optical power meter and stores the data as a temperature-optical output characteristic of the semiconductor laser while drives the heating device. The control unit also derives data of the optical output of the semiconductor laser produced through the optical fiber from time to time while solder is fused and solidified when the end of the optical fiber is soldered and fixed to the predetermined position in the package.
