摘要： An ultra-thin glass sheet is formed using a roll-to-roll glass soot deposition and sintering process. The sintering involves initially heating and sintering one or more central segments of a glass soot sheet, and progressively heating and sintering glass soot sheet segments that are located laterally or axially adjacent to previously-sintered segments such that, along respective width directions of the glass soot sheet, only a portion of the width is sintered at a given time interval during the heating.

摘要： Light scattering inorganic substrates and articles comprising soot particles and methods for making light scattering inorganic substrates and articles comprising soot particles useful for, for example, photovoltaic cells. The method for making the substrates and articles comprises providing an inorganic substrate comprising at least one surface, applying soot particles pyrogenically to the at least one surface of the inorganic substrate to form a coated substrate, and heating the soot particles to form the light scattering inorganic substrate. The invention creates a scattering glass surface that is suitable for subsequent deposition of a TCO and a thin film silicon photovoltaic device structure. The scattering properties may be controlled by the combination of substrate glass and soot composition, deposition conditions, patterning of the soot, and/or sintering conditions.

摘要： The strain-managed optical waveguide assemblies of the present invention utilize a large-mode-area (LMA) optical fiber that is annealed in a first bending such that the fiber in that configuration has substantially no axial strain. A fiber support member is then used to support the annealed LMA optical fiber in a second bending configuration that forms within the LMA optical fiber an axial strain profile that reduces stimulated Brillouin scattering (SBS) as compared to the first bending configuration, and that also preferably causes the LMA optical fiber to operate in a single mode. The LMA optical fiber may have a double-clad configuration and include a doped core that serves as a gain medium. The strain-managed optical waveguide assembly can then be used to constitute a fiber amplifier that mitigates the SBS penalty associated with high-power fiber-based optical systems. The strain-managed waveguide assembly can also provide for thermal management in high-power applications, and can be used to control SBS by controlling the temperature profile along the length of the LMA optical fiber in a manner that mitigates SBS.

摘要： A method of fabricating a microstructure for an optical waveguide such as a photonic bandgap fiber is provided. The method includes the steps of assembling a stack of capillary tubes having substantially identical dimensions, fusing and redrawing the stack into a preform having a plurality of parallel holes of equal diameter, selecting a pattern of the holes for etching in order to increase their diameter, and plugging the unselected holes at one end of the preform against the flow of a pressurized etching fluid. Such plugging of the unselected holes is accomplished applying a layer of a gel-like sealant over the end of the preform, and then pushing the sealant into the holes to form sealant plugs in all of the holes. The sealant plugs are then removed from the selected holes by punching the sealant plugs out of the selected holes. The selected holes are then etched by conducting a pressurized flow of etching fluid to the end of the preform such that etching fluid flows only through the pattern of selected holes. The resulting preform is then fused and drawn into an optical waveguide, where the pattern of etched and unetched holes may form, for example, the microstructure for a photonic bandgap optical fiber.
