Effect of coupling coefficients on self-pulsation characteristics in multisection DFB lasers with amplifying optical feedback
2006
Pulsation characteristics of multi-section DFB lasers with amplifying optical feedback have been investigated for various coupling coefficients. Wide current ranges showing stable pulsations could be obtained in the multi-section DFB lasers with anti-phase gratings compared to those with in-phase gratings and index gratings.
