Relationship between initial thermal characteristics and lifetime projection of semiconductor laser diodes
A novel reliability projection model of semiconductor laser diodes (LD) is presented. By correlating initial thermal characteristics and long-term degradation, a relationship between LD degradation and ambient temperature has been investigated. The proposed model is found to be efficient for the reliability projection of LDs, which requires a thermal characterization only at t=0.
