1.3-MU-M INGAASP FABRY-PEROT LASERS WITH REDUCED PULSE JITTER AND POWER PENALTY

The pulse jitter and bit-error-rate performances of a 1.2 Gbit/s lightwave transmission system using 1.3 mum InGaAsP Fabry-Perot (FP) lasers with Zn-doped active layers were investigated experimentally. It was found that the pulse jitter and the resulting power penalty were strongly dependent on the carrier lifetime of the lasers. This suggests that doped-active FP lasers with decreased carrier lifetime may be usable in a wider range of gigabit lightwave applications than previously considered.
