摘要： A component can include a substrate and a conductive via extending within an opening in the substrate. The substrate can have first and second opposing surfaces. The opening can extend from the first surface towards the second surface and can have an inner wall extending away from the first surface. A dielectric material can be exposed at the inner wall. The conductive via can define a relief channel within the opening adjacent the first surface. The relief channel can have an edge within a first distance from the inner wall in a direction of a plane parallel to and within five microns below the first surface, the first distance being the lesser of one micron and five percent of a maximum width of the opening in the plane. The edge can extend along the inner wall to span at least five percent of a circumference of the inner wall.

摘要： An apparatus for producing the glass soot used in the formation of optical fiber includes a burner with an internal atomizer. The atomizer includes an outer tube having a nozzle at an end thereof, and an inner tube located within the outer tube and having a closed end restricting fluid flow therethrough and defining a cylindrical sidewall having radially extending apertures spaced there along. The outer tube receives the glass-forming mixture in liquid form and the inner tube receives an atomizing gas which flows through the apertures in the sidewall of the inner tube and atomizes the glass-forming mixture as the glass-forming mixture travels through the outer tube.

摘要： An optical waveguide designed to generate positive dispersion when operated in a high order mode. The optical waveguide in one embodiment is designed to generate positive dispersion slope, in another embodiment to generate negative dispersion slope and in yet another embodiment nominally zero dispersion slope. In one embodiment the high order mode is the LP02 mode and in another embodiment the high order mode is the LP03 mode. In another embodiment the optical waveguide is a few mode fiber. In an exemplary embodiment the optical waveguide is used in combination with a mode transformer, such as a transverse mode transformer to achieve the desired high order mode.

摘要： A method that provides a new way to embed rare earth fluorides into silicate (or germania-doped silica) glasses by means of solution chemistry. Embedding rare earth fluorides into a silicate (or germania-doped silica) glass comprises the following steps. First, form a porous silicate core preform. Second, submerge the preform into an aqueous solution of rare earth ions. Third, remove the preform from the solution and wash the outside surfaces of the preform. Fourth, submerge the preform into an aqueous solution of a fluorinating agent to precipitate rare earth trifluorides from the solution and deposit in the pores or on the wall of the preform. This is followed by drying.

摘要翻译： 一种通过溶液化学提供将稀土氟化物嵌入硅酸盐（或氧化锗掺杂二氧化硅）玻璃的新方法的方法。 将稀土氟化物嵌入硅酸盐（或掺锗二氧化硅）玻璃中包括以下步骤。 首先，形成多孔硅酸盐芯预制件。 第二，将预成型件浸入稀土离子的水溶液中。 第三，从溶液中取出预型件并洗涤预成型件的外表面。 第四，将预制件浸入氟化剂的水溶液中以从溶液中沉淀出稀土三氟化物，并沉积在预制件的孔或壁上。 然后干燥。
