    摘要: Vertical cavity surface emitting lasers (VCSELs) and methods of making the same are described. The VCSELs include reliability-enhancing layers that perform specific functions at one or more critical locations within a VCSEL structure to reduce or prevent defect formation and migration that otherwise might degrade VCSEL performance, for example, by increasing optical absorption in the mirror stacks or by degrading the electro-optic properties of the active region. In particular, the reliability-enhancing layers are configured to perform one or more of the following functions within the VCSEL structure: gettering (i.e., removing defects or impurities from critical regions), strain balancing (i.e., compensating the lattice mismatch in the structure to minimize strain), and defect suppression (i.e., creating alloys that reduce the formation of defects during growth or post-growth activities). By strategically positioning one or more appropriately configured reliability-enhancing layers with respect to an identified defect source, the invention enables VCSEL structures to be modified in a way that enhances the reliability and performance of VCSEL devices.

    摘要: A stemming device for holes which device comprises at least one layer of aesilient material capable of forming a seal in conjunction with the wall of a hole, the seal being characterized in that it prevents, minimizes or substantially retards the flow of flowable, pourable or pumpable material from the hole. The device is used to stem a hole by positioning the same in the hole in a manner such that said stemming device forms a seal in conjunction with the wall of the hole capable of preventing, minimizing or substantially retarding the flow of flowable, pourable or pumpable material from the hole.
