    Abstract: According to embodiments, a method of making a microstructured glass article 100 includes bundling M bare optical fibers in a fiber bundle, wherein M is an integer greater than 100. Thereafter, the fiber bundle may be inserted in a cavity of a soot preform. The soot preform may have a density of less than or equal to 1.5 g/cm3 and comprise silica-based glass soot. The soot preform and inserted fiber bundle may then be consolidated to form a microstructured glass article preform. The microstructured glass article preform may then be drawn into the microstructured glass article 100 comprising M core elements 102 embedded in a cladding matrix 104.

    Abstract: A method is provided that includes: forming a low-index trench region (112) with a first density; forming an inner barrier layer (116a) comprising silica around the trench region at a second density greater than the first density; depositing silica-based soot around the first barrier layer to form an overclad region (114) at a third density less than the second density; inserting a core cane (102) into a trench-overclad structure; forming an outer barrier layer (116b) comprising silica in an outer portion of the overclad region at a fourth density greater than the third density; flowing a down dopant-containing gas through the trench-overclad structure (110) to dope the trench region with the down dopant, and wherein the barrier layers (116a,116b) mitigate diffusion of the down-dopant into the overclad region (114); and consolidating the trench-overclad and the core cane. A method of making a consolidated trench-overclad structure with inner and outer barrier layers is also provided.

    Abstract: A method of forming an optical fiber includes the steps of forming a soot blank of a silica-based cladding material, wherein the soot blank has a top surface and a bulk density of between 0.8 g/cm2 and 1.6 g/cm3. At least one hole is drilled in the top surface of the soot blank. At least one core cane member is positioned in the at least one hole. The soot blank and at least one soot core cane member are consolidated to form a consolidated preform. The consolidated preform is drawn into an optical fiber.
