Dynamics of index coupled DFB lasers with minimal spatial hole burning
Abstract
Spatial hole burning in quarter-wave phase-shifted DFB lasers can be significantly reduced by spatially varying the coupling coefficient in the longitudinal direction. For such a laser, time dependent spatial hole burning is examined using a large signal dynamic model established earlier. The transient power changes, frequency chirp during gain switching, and side mode suppression ration at steady state are also simulated.
