A method of fabricating an optical fibre preform is disclosed comprising using a subtractive process on an optical monolith to define therein at least a transverse section of the optical fibre preform, wherein the transverse section comprises at least two regions with different refractive indexes. An optical fibre preform fabricated in accordance with the method is also disclosed along with a method of assembling optical components using a subtractive process to define a first interconnecting feature in or for use with a first optical component; using a subtractive process to define a second interconnecting feature in or for use with a second optical component; and coupling the first and second components together using the first and second interconnecting features such that the coupling dictates a passive alignment of the first and second components.

Described herein are articles and methods of making articles, for example glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier are bonded together using a modification (coating) layer, for example a coating layer comprising a cationic surfactant or a coating layer comprising an organic salt, and associated deposition methods. The modification layer bonds the thin sheet and carrier together with sufficient bond strength to prevent delamination of the thin sheet and the carrier during high temperature (? 500° C.) processing while also preventing formation of a permanent bond between the sheets during such processing.

A method of assembling together a first part and at least one second part that are made of materials compatible with bonding by molecular adhesion includes a step of pressing a first surface of the first part against a second surface of the second part so as to create molecular bonds at an interface between the parts, and a step of consolidating the interface bonding as created in this way by heat treatment. The consolidation includes a step of emitting a power laser beam towards an impact point forming a portion of the outline of the interface, and a step of moving the impact point along the outline of the interface.

A manufacturing method of a glass panel unit of the present invention includes a bonding step, a pressure reduction step, and a sealing step. In the bonding step, a first substrate and a second substrate are hermetically bonded together with a seal having a frame shape. In the pressure reduction step, a pressure in an inside space formed between the first substrate and the second substrate is reduced through an exhaust port. In the sealing step, sealant disposed between the first substrate and the second substrate is deformed, and the sealant thus deformed seals an opening of the exhaust port.

The invention provides a method of processing glass that involves forming a flexible gel layer on a flexible glass sheet to create a glass-gel sheet; rolling-up the glass-gel sheet into the form of a roll; placing the roll in a dryer; and drying the flexible gel layer so as to form a flexible aerogel layer. Some embodiments provide a glazing unit that includes a glass-aerogel sheet located between first and second panes of the glazing unit, where the glass-aerogel sheet includes a flexible glass sheet and a flexible aerogel layer on the flexible glass sheet. In such embodiments, the first and second panes each have thicknesses that are greater than a thickness of the flexible glass sheet. Other embodiments provide a glass assembly having a flexible aerogel layer on a flexible glass sheet, with the flexible glass sheet being laminated to a glass pane.
