Coupling-coefficients in gain-coupled DFB lasers: inherent compromise between coupling strength and loss

Author

Abstract
A theoretical analysis of the gain-coupling coefficient kappa-(gain)L for DFB lasers with first-order, rectangular, gain, or loss gratings is presented. For the structure with gain grating, the dependence of kappa-(gain) on the modal gain g(mod) has been into account for the first time. In both structures, an inherent compromise between coupling strength and extra modal loss is found. The results show that significant kappa-(gain)L values are feasible, allowing to benefit from the unique features of gain-coupled DFB lasers.
