An LD module capable of generating a good optical waveform at a high speed of about 10 Gbit/s or higher in which a damping resistor is disposed in parallel with a laser-diode device in the inside of a laser-diode module, the damping resistor being preferably disposed between the connection point of the high-frequency transmission line and the terminating resistor, and the ground. |
