Abstract :
Degradation modes of 1.3 ¿m and 1.55 ¿m buried heterostructure (BH) distributed feedback (DFB) lasers are discussed and several degradation modes are clarified. DFB lasers essentially fail due to BH interface degradation in the same manner as BH Fabry-perot (FP) lasers. Additional degradation modes peculiar to DFB lasers are found to exist.
