We demonstrate the use of low-speed optoelectronic device to process high-speed optical signals with the use of time- and wavelength-interleaved pulses. Results show that the requirement on electronic bandwidth has been reduced using the wavelength division approach.
All-optical signal regeneration has been demonstrated with wavelength multicasting at 6/spl times/10 Gb/s using a single electroabsorption modulator. The output extinction-ratio, the linewidth and the pulse shape are improved and a negative power penalty is obtained.
Summary form only given. In summary a novel scheme for the generation of dual-wavelength picosecond optical laser diode pulse train was demonstrated. Emission of additional wavelengths was expected by further increase of dispersion in the external cavity. This work will have potential applications in high-speed WDM communication sytems.
