Abstract:
Layered glass structures and fabrication methods are described. The methods include depositing soot on a dense glass substrate to form a composite structure and sintering the composite structure to form a layered glass structure. The dense glass substrate may be derived from an optical fiber preform that has been modified to include a planar surface. The composite structure may include one or more soot layers. The layered glass structure may be formed by combining multiple composite structures to form a stack, followed by sintering and fusing the stack. The layered glass structure may further be heated to softening and drawn to control linear dimensions. The layered glass structure or drawn layered glass structure may be configured as a planar waveguide.
Abstract:
An apparatus includes a fiber feeding system to deposit a fiber on an edge of the glass article and a laser system. The laser system is positioned to project a first and a second laser beam onto a first and a second side of the fiber, respectively. The laser system is positioned to project a third laser beam onto the edge of the glass article. A method includes advancing a glass article relative to a fiber; positioning the fiber in relation to an edge of the glass article, contacting a first side of the fiber with a first laser beam, contacting a second side of the fiber with a second laser beam, depositing the fiber on the edge of the glass article, and contacting the edge of the glass article with a third laser beam.
Abstract:
A method of forming a sealed device comprising providing a first substrate having a first surface, providing a second substrate adjacent the first substrate, and forming a weld between an interface of the first substrate and the adjacent second substrate, wherein the weld is characterized by ((σ tensile stress location )/(σ interface laser weld )) interface laser weld > 10 MPa or > 1 MPa where σ tensile stress location is the stress present in the first substrate and σ interface laser weld is the stress present at the interface. This method may be used to manufacture a variety of different sealed packages.

Dicho procedimiento comprende la aplicación de dichas formulaciones sobre baldosascerámicas mediante la técnica de decoración por chorro de tinta inkjet, y la cocción posterior de los sustratos así obtenidos mediante tratamientos térmicos de mono-cocción.
Abstract:
A method includes forming a glass article. The glass article includes a core and a clad adjacent to the core. The core includes a first glass composition. The clad includes a second glass composition different than the first glass composition. A degradation rate of the second glass composition in a reagent is greater than a degradation rate of the first glass composition in the reagent.
Abstract:
A method of coating film in a roll. A film is wound into a roll with gaps between the layers of the film in the roll. A fluid is forced through the roll such that the fluid deposits a coating on at least one side of the film.
Abstract:
An optical member including a porous glass layer on a base member is provided, wherein the reflectance is reduced and a ripple is suppressed. The optical member is provided with a base member and a glass layer holding a transparent material in the inside of a porous structure disposed on the base member, wherein in the thickness direction of the glass layer, the porosity in the base member side with respect to the center line of the glass layer in the thickness direction is smaller than the porosity in the side opposite to the base member with respect to the center line of the glass layer in the thickness direction.
Abstract:
A glass-coated gasket (212) comprises a gasket main body (116) defining an inner hole (114) and having a first contact (118) surface and a second contact surface (119) opposite the first contact surface (118), and a glass layer formed over at least a portion of one of the first contact surface (118) and the second contact surface (119). The glass layer comprises a low melting temperature glass. A hermetic package comprises a substrate/glass-coated gasket/substrate structure that can be sealed using a thermo-compressive sealing step.
