Abstract:
An optical member, a glass fiber, and an optical amplifier, which are made of a sulfuric chalcogenide glass having no metamorphic layer on the surface, are provided by a manufacturing method including the steps of preparing a matrix made partially or entirely of a chalcogenide glass or oxychalcogenide glass, and attaching sulfur or sulfide to at least a portion of a surface of the matrix in a physical or chemical manner. A glass fiber is manufactured by a method including the steps of preparing a matrix made partially or entirely of a chalcogenide glass or oxychalcogenide glass, and attaching sulfur or sulfide to at least a portion of a surface of the matrix in a physical or chemical manner and concurrently drawing the matrix.
Abstract:
Disclosed is a method of manufacturing a crystallized glass for a secondary battery. The secondary batter include a solid electrolyte comprising sulfide, which can be prepared by synthesizing sulfides using thermal energy and vapor pressure as energy sources. The method of the present invention is suitable for manufacturing a crystallized glass for use as the electrolyte comprising sulfide of the secondary battery. The method includes dispersing two or more kinds of sulfides in a solvent and synthesizing the sulfides under conditions of a temperature equal to or greater than a boiling point of the solvent and high pressure greater than standard atmospheric pressure.
Abstract:
Preforms are obtained (900) and drawn (910). Different preforms of different materials are also obtained (920) and drawn (930). The preforms are then stacked (950) and inserted into a tube (960). The result is then draw (970) into a lightguide that can be an optical fiber or laser or amplifer.
Abstract:
In general, in one aspect, the invention features a method that includes exposing a surface to a first gas composition under conditions sufficient to deposit a layer of a first chalcogenide glass (240) on the surface, and exposing the layer of the first chalcogenide glass (240) to a second glass composition under conditions sufficient to deposit a layer of a second glass (230) on the layer of the first chalcogenide glass, wherein the second glass is different from the first chalcogenide glass.
Abstract:
A system and method for preparing chalcogenide glass are provided that allow for larger quantities of glass to be produced with lower production costs and less risks of environmental hazards. The system includes a reaction container operable to hold chalcogenide glass constituents during a glass formation reaction, a stirring rod operable to mix the contents of the reaction container, a thetmocouple operable to measure the temperature inside the reaction container, and a reaction chamber operable to hold the reaction container. The method includes placing chalcogenide glass constituents in a reaction container, heating the chalcogenide glass constituents above the melting point of at least one of the constituents, promoting dissolving or reaction of the other constituents, stirring the reaction melt, maintaining an overpressure of at least one atmosphere over the reaction melt, and cooling the reaction melt to below the chalcogenide glass transition temperature.
