  • Abstract Due to dramatic growth of capacity in optical fiber communication, the fiber dispersion has become one of major factors affecting the quality of optical signal transmission with different modulation scheme, leading to the importance in controlling optical chirp. Among the elements used for optical fiber communications, electroabsorption modulator (EAM) and semiconductor optical amplifier (SOA) are served as optical amplitude and phase modulation. In this work, EAM-integrated SOA is used to realize the pre-chirp technique through their inherently reversed phase modulation as well as amplitude modulation.
    In the experiment, tunable optical filter and a 10Gb/s data pattern are used for extracting the frequency chirp of the timely signal. With the positive chirp operation in EAM, it is found that the overall chirp of EAM-integrated SOA can be varied from 3GHz to -9GHz by adjusting current injection through SOA. Also, as inspecting the 10Gb/s pattern, the pattern effect can also be controlled by the reversed carrier dynamics between EAM and SOA. Finally, a 10Gb/s data transmission with 43km transmission is demonstrated by using such pre-chirp technique, showing that such technique can be applied to other type signal processing.
