Disclosed are AZO films deposited on a transparent substrate by pulse DC using an oxide target with a composition in the range 0.5-2 wt % AlO, desirably at temperature above 325&#xb0; C., resulting in films showing columnar grain structure with columns extending from the top to the bottom of the film, and small lateral grain size (less than 70 nm from substrate to top of film). The film has low resistivity at less than 10 Ohm/square at a thickness less than 400 nm, resistivity is desirably unchanged by annealing at temperatures of up to 450&#xb0; C.

Glass web including a first glass-web portion (), a second portion (), and a splice joint () coupling the first glass-web portion to the second portion, wherein the slice joint includes a splice member () with at least one gas-permeable attachment portion. In further examples, methods of splicing a first glass-web portion to a second portion include the step of splicing the first glass-web portion to the second portion with a splice member, wherein the step of splicing includes attaching a gas-permeable attachment portion of the splice member to the first glass-web portion.

Germanium-silicon oxide, germanium-silicon oxynitride and silica-germania-titania materials and oxynitride materials suitable for fabricating optical waveguides for liquid crystal based cross-connect optical switching devices have a refractive index of from about 1.48 to about 1.52 at 1550 nm, and a coefficient of thermal expansion at room temperature of from about 3&times;10 &deg; C. to about 4.4&times;10 &deg; C. . The compositions are adjusted so that the refractive index of the germanium-silicon oxide, germanium-silicon oxynitride or silica-germania-titania material is closely matched to the refractive index of a typical liquid crystal material whereby improved optical performance of a liquid crystal based cross-connect optical switching device is achieved. The coefficient of thermal expansion of the germanium-silicon oxide, germanium-silicon oxynitride, or silica-germania-titania material is closely matched to the coefficient of thermal expansion of silicon, whereby strain induced birefringence caused by thermal stresses is reduced or avoided.
