Abstract :
The quality of 1.5 /spl mu/m Fabry-Perot lasers for application in the optical access network has been improved by lifetests and failure analysis on two groups of buried structure (buried mushroom-BMS and buried ridge-BRS) devices. The comparison between the degradation levels and the failure mechanisms (interface defects, leakage paths) suggested the choice of the less weak BRS structure and the technological improvements to be applied. A new group of BRS devices showed less defectivity and good stability during the lifetest.
