摘要： An optical fiber termination connector includes an elongated structure with chamber extending therethrough open at both ends, a fiber disposed in the chamber and spaced therefrom, a solid first material disposed in the chamber around the fiber, and an air gap in the chamber around the end of the fiber. The process includes the steps of locating a fiber in a chamber disposed vertically, with the end of the fiber extending beyond the lower portion of chamber; dipping a lower portion of the chamber into a first material in liquid form so that the first material enters the lower portion of the chamber to a level below an exit port located in the lower portion of the chamber; solidifying the first material disposed in and around the chamber and the fiber; above the solid first material; polishing the lower end of the fiber until it is flush with the chamber at the lower thereof; and removing the first material to form an air gap between the fiber and the lower portion of the chamber. The air gap is large enough to allow independent thermal expansion of the fiber.

摘要： A functionally doped polycrystalline ceramic laser medium and method of making thereof are provided. The medium includes a solid state polycrystalline Ytterbium doped Yttria or Scandia (Yb:Y2O3 or Yb:Sc2O3) laser medium with a discrete or continuous gradient doping profile and methods for manufacturing the same. The doping profile can be two- or three-dimensional and can vary depending upon the laser geometry, the pumping scheme, and the benefits to be desired from the laser medium's structure. The grading direction can be linear, axial, radial, or any combination thereof. The material can be made from a combination of doped and undoped solid shapes, loose powders, and green shapes, and can be diffusion bonded or densified to a desired final shape using techniques such as pressureless sintering, hot pressing, hot forging, spark plasma sintering, and hot isostatic pressing (HIPing), or their combinations.

摘要： A thermally stable chalcogenide glass, a process for making the same, and an optical fiber drawn therefrom are provided. A chalcogenide glass having the composition Ge(5−y)As(32−x)Se(59+x)Te(4+y) (0≦y≦1 and 0≦x≦2) is substantially free from crystallization when it is heated past the glass transition temperature Tg or drawn into optical fibers. A process for making the thermally stable chalcogenide glass includes purifying the components to remove oxides and scattering centers, batching the components in a preprocessed distillation ampoule, gettering oxygen impurities from the mixture, and heating the components to form a glass melt. An optical fiber formed from the chalcogenide glass is substantially free from crystallization and exhibits low signal loss in the near-infrared region, particularly at wavelengths of about 1.55 μm.
