Abstract: An anti-resonant hollow core optical fiber preform that includes an outer cladding, a plurality of structural tubes, and a central support tube. The outer cladding has a length, a central longitudinal axis, and a hollow interior. The plurality of structural tubes are disposed within the hollow interior of the outer cladding, the plurality of structural tubes each having a length that extends the length of the outer cladding. And the central support tube is disposed within the hollow interior of the outer cladding such that the plurality of structural tubes are disposed radially outward of the central support tube, the central support tube having a length that extends along the central longitudinal axis of the outer cladding. Furthermore, the length of the central support tube is less than the length of the outer cladding.

Abstract: Multicore optical fibers are disclosed that have randomly arranged cores within a cladding matrix. In some cases, the cores are defined by air lines formed in a glass matrix. The cores can have an edge-to-edge spacing designed so that the multicore optical fiber operates in either a weak-coupling regime or a strong-coupling regime. Imaging systems and optical fiber communication systems that utilize the multicore fibers disclosed here are also presented.

Abstract: According to embodiments, a method of making a microstructured glass article 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 comprising M core elements embedded in a cladding matrix.

Abstract: A mode division multiplexing system that includes a transmitter system, a receiver system and an optical link that optically connects the transmitter and receiver systems. The optical link includes a rectangular-core optical fiber having a rectangular core with a short dimension and a long dimension. The rectangular-core optical fiber supports only a single mode in the short dimension and multiple modes in the long dimension. A method of transmitting optical signals includes converting single mode optical signals to respective multimode optical signals each having a select spatial mode as defined by the rectangular-core optical fiber. The multimode optical signals are multiplexed and transmitted from the transmitter system to the receiver system over the rectangular-core optical fiber where the multimode optical signals are demultiplexed and converted back to single mode optical signals, which are then detected by respective receivers. A rectangular-core optical fiber is also disclosed.

Abstract: Described herein are aqueous acidic glass etching solutions or media comprising HF and H2SO4, wherein HF is present in concentrations not exceeding about 1.3M. The etching solutions are used to treat glass articles such as thin glass sheets at above-ambient temperatures to etch slight thicknesses of surface glass therefrom, the etching solutions exhibiting improved stability against dissolved glass precipitation and rapid glass removal rates at slightly elevated temperatures.

Abstract: A method is provided that includes: forming a low-index trench region with a first density; forming an inner barrier layer 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 at a third density less than the second density; inserting a core cane into a trench-overclad structure; forming an outer barrier layer 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 to dope the trench region with the down dopant, and wherein the barrier layers mitigate diffusion of the down-dopant into the overclad region; and consolidating the trench-overclad and the core cane.
