ABSTRACT:
An optical transmission module is constructed in a configuration wherein a semiconductor laser is mounted on a stem-side emitter loading portion of a pole provided on a stem and wherein light emitted forward from the semiconductor laser is outputted through a condenser lens and others. A monitor photodiode is mounted on a receiver loading portion of the pole on the forward side of the semiconductor laser and the photodiode detects part of the light emitted forward from the semiconductor laser, to monitor the operating condition of the semiconductor laser. This configuration achieves decrease in the length of a lead pin and thus restrains deterioration of the waveform of the drive current to the semiconductor laser.
