    摘要： A glass sheet is formed using a roll-to-roll glass soot deposition and sintering process. The glass sheet formation involves forming a first glass soot layer (152) on a deposition surface (122) of a soot-receiving device (120), removing the first glass soot layer (152) from the deposition surface (122), and forming a second glass soot layer (162) on the unsupported first glass soot layer. The resulting composite glass soot sheet (174) is heated to form a sintered glass sheet. The glass sheet can be a substantially homogeneous glass sheet or a composite glass sheet having layer-specific attributes.

    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.

    摘要翻译： 提供了一种制造用于诸如光子带隙光纤的光波导的微结构的方法。 该方法包括以下步骤：组装具有基本上相同尺寸的毛细管堆叠，将叠层熔合并重新拉伸成具有多个相等直径的平行孔的预成型件，选择用于蚀刻的孔的图案以增加其直径， 并且在预成型件的一端处与加压蚀刻流体的流动堵塞未选择的孔。 在预成型件的端部上施加一层凝胶状密封剂，然后将密封剂推入孔中以在所有孔中形成密封塞，实现未选择的孔的这种堵塞。 然后通过从选定的孔中冲出密封塞，将所选择的孔中的密封塞从所述孔中除去。 然后通过将加压流动的蚀刻流体引导到预成型件的端部来蚀刻所选择的孔，使得蚀刻流体仅流过选定孔的图案。 然后将所得的预制件熔合并拉入光波导，其中蚀刻和未蚀刻孔的图案可以形成例如光子带隙光纤的微结构。
