Abstract
Cross-section TEM analysis was applied to the dice of degraded DH GaAs/GaAlAs oxide-stripe laser diodes to enable a deeper understanding of the origin of chip-related failures in the field operation. The technique enabled the growth of dislocation loops confined inside the active layer to be identified as the failure mechanism responsible for the degradation.
