A composite article includes an inorganic non-metallic article and a resin article. The resin article is connected to the inorganic non-metallic article. The inorganic non-metallic article includes at least one connecting surface. At least a portion of the connecting surface comprises groove-peak like microstructures. At least one of the microstructures comprises a rough and/or porous surface having at least one of a roughness element and a porous structure.

A plasmonic sensor, having at least a substrate, a laser processed active surface area on the said substrate, and a metal coating on the activate surface, where the laser processed surface is fabricated by means of short laser pulses in such a way that in a shallow layer of the surface material, the viscosity is reduced and under the influence of the same pulse, which was used to reduce the viscosity, or a successive incident one or more pulses a self-organized, stochastic nanostructure is formed, which has features smaller than 1 μm. In some implementations, the substrate material is amorphous, such as soda-lime glass or similar. Also disclosed is a slide and/or a slip cover, which are used in microscopy, for forming the active sensor area on top surface of it.

Methods and devices for producing a composite pane having a functional coating are presented. The functional coating is applied to part of a surface of a base pane, and a first pane is cut out from the base pane while introducing a frame-shaped peripheral coating-free region into the functional coating having an inner region that is not adjacent a side edge of the first pane. The surface of the first pane with the functional coating is then bonded via a thermoplastic intermediate layer to a surface of a second pane.

A method of processing a glass material includes guiding and/or focusing light from a light source to glass material in a hot stage of a processing system, where the light source provides light at a wavelength λ that interacts with crystals that may be formed in the glass material. The method includes collecting and/or guiding light directed from the glass material in the hot stage to a wavelength separator, and separating the light directed from the glass material to provide a spectrum δ having wavelengths that are within about twenty nanometers of the wavelength λ. The method includes observing with a detector light of the spectrum δ to identify nano-scale shifts in the wavelength λ caused by interaction with crystals, if present, within the glass material in the hot stage of the processing system.

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.sub.tensile stress location)/(σ.sub.interface laser weld))<<1 or <1 and σ.sub.interface laser weld>10 MPa or >1 MPa where σ.sub.tensile stress location is the stress present in the first substrate and σ.sub.interface laser weld is the stress present at the interface. This method may be used to manufacture a variety of different sealed packages.

A method of manufacturing a partially textured glass article that includes (a) providing partially textured mother glass substrate that includes a first main surface and a second main surface which are opposed to each other; (b) irradiating the first main surface of the glass substrate with a laser to form a separating line on the first main surface that defines contour lines and extends from the first main surface to the second main surface dividing the glass article from the glass substrate, the glass article being a size smaller than the mother glass substrate; and (c) separating the partially textured glass article is separated from the mother glass substrate by the separating line. The method allows cutting a large partially textured mother glass substrate, with high precision, into smaller articles of partially textured glass at a requested size.

A method of manufacturing a cover window for a display device includes: providing a glass substrate having a bendable area and a flat area; modifying the bendable area by irradiating the glass substrate with a beam; and etching the bendable area to have a thinner thickness than the flat area. The bendable area may have a faster etch rate than the flat area due to the modifying of the bendable area.

The method for inscribing a waveguide into a media glass substrate generally has the steps of: relatively moving a femtosecond laser beam along a surface of the media glass substrate while maintaining the focus of the laser beam at a depth of less than the surface, wherein the waveguide has a loss of less than 0.2 dB/cm when measured at a wavelength of light signal propagating in the waveguide during normal use of the waveguide. Particularly, the method can have varying writing parameters according to whether the waveguide is single-mode or multi-mode.

A method for strengthening an edge of a glass laminate including a glass core layer positioned between a first glass clad layer and a second glass clad layer may include forming a channel in the edge of the glass laminate. Sidewalls of the channel may be formed from the first glass clad layer and the second glass clad layer. Glass filler material having a filler coefficient of thermal expansion greater than a core coefficient of thermal expansion may be positioned in the channel. The glass filler material and the sidewalls of the channel may be fused to the second glass clad layer thereby forming an edge cap over the channel. The edge of the glass laminate is under compressive stress after the glass filler material is enclosed in the channel.
