In general, in one aspect, the disclosure features a fiber waveguide having a waveguide axis, including a core extending along the waveguide axis and a confinement region extending along the waveguide axis surrounding the core. The confinement region includes a periodic structure along a radial direction extending from the waveguide axis and each period in the periodic structure includes a layer of a chalcogenide glass and a layer of a polymer.

Fiber waveguide formed from chalcogenide glass and polymer

In one aspect, the invention features a fiber waveguide having a waveguide axis, including a first portion extending along the waveguide axis, and a second portion different from the first portion extending along the waveguide axis surrounding the first portion, wherein at least one of the first and second portions comprises a chalcogenide glass selected from the group consisting of Selenium chalcogenide glasses and Tellurium chalcogenide glasses, both the first and second portions have a viscosity greater than 10Poise at some temperature, T, and the fiber waveguide is a photonic crystal fiber.

High index-contrast fiber waveguides and applications

High index-contrast fiber waveguides, materials for forming high index-contrast fiber waveguides, and applications of high index-contrast fiber waveguides are disclosed.

The present invention provides a vitrified-bonded abrasive tool wherein the abrasive grit portion comprises a thermally sensitive abrasive grain, such as sintered sol gel microcrystalline alpha alumina abrasive grain or superabrasive grain, and wherein the vitrified bond may be matured by firing at a temperature of about 700 to 1,100 &deg; C. The invention preferably is carried out with sintered sol gel microcrystalline alpha alumina abrasive grain and a phosphorous oxide-containing, alkaliborosilicate vitrified bond composition. In one embodiment, during firing at about 700 to 1,100 &deg; C., the vitrified bond of the invention comprises at least two immiscible, amorphous phases.

Vitrified bonded abrasive tools

A portable pencil pocket 10 has one or more compartments for holding pencils 40,42. The pocket is made of plastic webbing that is folded at one end to form a pocket 20 and at the other end to form a loop 22. A shower clip 50 holds the pocket 10 to an article of clothing, such as a belt loop or button hole.
