摘要：

We report the Improvement of frequency response characteristics of 2.5 Gbps modulator integrated distributed feedback (MI-DFB) laser modules using new impedance matching technique. Frequency responses for the fabricated module using the '+' shaped microstrip line for impedance matching have been significantly improved such as the RF return loss of I I dB and the 3 dB frequency bandwidth of 4.1 GHz, compared to 6 dB return loss and 1.5 GHz bandwidth for the conventional module. These results can be also well predicted by the simulation of frequency responses for the modules. From the fabricated MI-DFB laser modules, good transmission performance has been obtained up to 640 km.
