Abstract :
We demonstrate the results of an analysis of laterally-coupled distributed feedback (LC-DFB) lasers with higher order gratings, including the effects of radiating partial waves. We determine grating geometries that result in lasers with improved performance and fabrication-tolerance. We also find that the addition of a lambda/4 phase-shift will generally diminish the performance of LC-DFB lasers with higher order gratings.
