Microstructured glass articles with at least 100 core elements and methods for forming the same

Abstract:

According to embodiments, a method of making a micro structured 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 micro structured glass article preform may then be drawn into the microstructured glass article 100 comprising M core elements 102 embedded in a cladding matrix 104.
