Abstract
Electroabsorption modulator (EAM)-distributed feedback (DFB) modules with r ecord-high bandwidth of 41 GHz have been developed. 40-Gb/s nonreturn to ze ro (NRZ) operation with 12-dB extinction ratio and -1.6-dBm average output power have been successfully achieved by optimizing the EAM length and detu ning. Clearly opened eye diagram was maintained even after 80-km nonzero di spersion shifted fiber (NZ-DSF) transmission with dispersion compensation. 40-GHz short pulse trains with 6-ps pulsewidth have been also generated by sinusoidal electrical modulation.
