Abstract :
A record high modulation bandwidth of over 50 GHz has been achieved for EAM-DFB lasers in the chip-on-carrier level by optimizing the device parameters. The packaged module has shown a record high modulation bandwidth of 45 GHz and dynamic extinction ratio of 9 dB at Vpp of 3.9 V. The 40 Gb/s NRZ-signal 4 km-transmission with standard SM fiber has been demonstrated. This 40 Gb/s EAM-DFB module is believed very promising for 40 Gb/s short distance fiber transmission.
