  • Abstract
    A theoretical analysis of the properties of DBR filters and DFB amplifiers with gain gratings is presented. The results show that, contrary to the case of devices with only an index grating, no compromise is needed between selectivity and peak reflectivity. The properties of active DBR filters improve considerably if gain coupling is introduced
