Abstract :
To study the above-threshold operation of DFB lasers, we have developed a multisection model which we present in detail. We have assessed the sensitivity to hole burning of various strongly coupled DFB lasers and explained their behavior both qualitatively and quantitatively, Good agreement is found with experimental results. It turns out that DFB lasers with a narrow stripe region are more stable than λ/4-shifted DFB lasers
