WAVELENGTH CHIRPING IN WAVELENGTH CONVERSION OF 10 GB S SIGNAL WITH SEMICONDUCTOR-LASER CONVERTER/

The chirping effects of wavelength converted 10 Gb/s signals in semico nductor wavelength converter on the waveform degradation after optical fiber transmission are investigated, The 10 Gb/s converted signal can be transmitted over 100 km with less than 2 dB power penalty in the c onverted wavelength region of 1.524 to 1.564 mu m when a broadly tunab le SSG-DBR laser wavelength converter and a dispersion shifted fiber a re used, It is also discussed how waveform degradation can be reduced when linewidth enhancement factor (alpha-parameter) of semiconductor l aser wavelength converter is reduced by using modulation-doped straine d MQW DFB lasers.
