英文摘要	Vertical cavity surface emitting lasers (VCSELs) include reliability-enhancing layers 48(54 Figure 3, 66 Figure 4) that perform specific functions at one or more critical locations within a VCSEL structure 40(50 Figure 3, 60 Figure 4) to reduce defect formation and migration, for example, by increasing optical absorption in the mirror stacks or by degrading the eletro-optic properties of the active region. Preferably, the reliability-enhancing layers 48(54 Figure 3, 66 Figure 4) are configured to perform one or more of the following functions within the VCSEL structure 40(50, 60): gettering (i.e., removing defects or impurities from critical regions), strain balancing (i.e., compensating the lattice mismatch in the structure to minimize stain), and defect suppression (i.e., creating alloys that reduce the formation of defects during growth or post-growth activities).
