  • Fiber optic connector and bonded cover
    Patent number: 9207407
    Abstract: A fiber optic assembly includes a connector and a cover bonded to an end face of the connector. The connector includes a ferrule, where an optical fiber extends through the ferrule and to the end face of the connector. An end of the optical fiber is polished proximate to the end face. The cover is bonded directly to the end face of the connector, and overlays the polished end of the optical fiber such that the cover protects the optical fiber, limits access of dust to the end face of the connector, and draws loose particulates from the end face upon removal of the cover.

  • Head-on laser shaping of optical surfaces of optical fibers, and related assemblies and methods
    Patent number: 9205610
    Abstract: Head-on laser shaping of optical surfaces on optical fibers, related assemblies and methods are disclosed. By “head-on laser shaping,” a laser beam is directed in a laser beam path collinear or substantially collinear to the longitudinal fiber axis of an end portion of an optical fiber. The end face of the end portion of optical fiber is exposed to the laser beam to laser shape a polished optical surface in the end face of the optical fiber. In this manner, the entire surface area of the end face of the optical fiber can be exposed to the laser beam during laser shaping, making it unnecessary unless desired, to rotate the optical fiber or laser beam during laser processing. The cross section energy distribution of the laser beam can also be controlled to laser shape an optical surface in the end face of the optical fiber of the desired geometry.

  • High static fatigue alumina isopipes
    Patent number: 9199868
    Abstract: Isopipes (13) for making a glass or a glass-ceramic using a fusion process are provided. The isopipes are made from an alumina material which has a higher static fatigue than existing alumina materials intended for use as isopipes. In particular, the alumina materials have times-to-failure (static fatigues) of greater than one hour at 1200° C. at an applied stress of 10,000 psi. These high levels of static fatigue allow alumina isopipes to replace zircon isopipes in the manufacture of high performance glass sheets by the fusion process, including glass sheets which are incompatible with zircon isopipes but compatible with alumina isopipes, e.g., chip and scratch resistant glass sheets which have high alkali contents.
