Abstract :
The spectrum behavior below the threshold in DFB lasers has been investigated. Analysis shows that the emission spectrum has peaks predicted by the threshold theory and proper valleys between large peaks. The results of our analysis should aid in the evaluation of DFB structure parameters.
