摘要:
The performance of high-speed lightwave transmission systems operating in the l.55-µm-wavelength region with conventional single-mode optical fiber can be influenced by the dynamic wavelength chirping exhibited by directly modulated semiconductor lasers. A recent paper presented the first detailed analysis of the bit error ratio performance of lightwave systems influenced by chirping-induced waveform distortion. This paper contributes additional numerical results which address the performance implications of the waveform distortion by considering the dependence of the receiver sensitivity on the decision time and decision threshold, the eye pattern, and the bit error ratio pattern. It is shown that the response of the linear receiver filter can influence the dependence of the receiver sensitivity on the decision time, and that there is a strong similarity between the eye pattern opening and the decision-time decision-threshold deformation of the bit error ratio pattern. The effects of the laser bias current, gain compression factor, and linewidth enhancement factor are also considered. © 1990 IEEE
