Abstract

It was verified for the first time that phase-shift value in directly modulated DFB-LDs affects their chirping characteristics and external optical feedback resistance due to the feedback effect of mirror loss (FER IL). Theoretical and experimental results clarified that the negative FEML achieved in lambda /8 phase-shifted DFB-LDs was able to improve the transmission performances and make the LDs more robust to external optical feedback, Isolator-free 80-km transmissions with a very low power penalty of less than 1-dBat bit error rate (BER) = 10(-10) was demonstrated with 2.5-Gb/s directly modulated 1.55-mum lambda /8 phase-shifted DFB-LDs.
