Abstract: A method of fabricating an optical fiber, the method including providing a core portion including a doped portion having greater than or equal to 1.6 wt. % of a halide dopant and eliminating seed precursor sites at an exterior surface of the core portion, the seed precursor sites forming seeds in the optical fiber, wherein the eliminating the seed precursor sites includes one or more of: (i) fabricating the core portion by densifying an exterior portion of a silica soot body prior to exposing the silica soot body to the halide dopant, and (ii) exposing the exterior surface of the core portion to a reactive etchant. The method further including forming an optical fiber preform by applying cladding material to the exterior surface of the core portion and drawing the fiber preform into the optical fiber.

Abstract: Embodiments of a filter for electromagnetic radiation are disclosed herein. The filter includes a first glass-ceramic substrate having a first refractive index, a second glass-ceramic substrate having the first refractive index, and a first region disposed between the first glass-ceramic substrate and the second glass-ceramic substrate. The first region has a second refractive index that is less than the first refractive index. Further, the second glass-ceramic substrate is arranged substantially parallel to and spatially disposed from the first glass-ceramic substrate. The filter transmits at least 70% of electromagnetic radiation within a band of frequencies and reflects at least 80% of electromagnetic radiation outside the band of frequencies. The band of frequencies is located within the frequency range of 20 GHz to 100 GHz.

Abstract: Methods for increasing the hydrolytic resistance of a glass article are disclosed. According to one embodiment, the method includes providing a glass article with a pre-treatment hydrolytic titration value. Thereafter, the glass article is thermally treated at a treatment temperature greater than a temperature 200 C less than a strain temperature of the glass article for a treatment time greater than or equal to about 0.25 hours such that, after thermally treating the glass article, the glass article has a post-treatment hydrolytic titration value that is less than the pre-treatment hydrolytic titration value.

Abstract: Embodiments of a glass-based article including a first surface and a second surface opposing the first surface defining a thickness (t) of about 3 millimeters or less (e.g., about 1 millimeter or less), and a stress profile, wherein all points of the stress profile between a thickness range from about 0·t up to 0.3·t and from greater than 0.7·t, comprise a tangent that is less than about −0.1 MPa/micrometers or greater than about 0.1 MPa/micrometers, are disclosed. In some embodiments, the glass-based article includes a non-zero metal oxide concentration that varies along at least a portion of the thickness (e.g., 0·t to about 0.3·t). In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a point between the first surface and the second surface and increases from the point to the second surface. The concentration of the metal oxide may be about 0.05 mol % or greater or about 0.5 mol % or greater throughout the thickness. Methods for forming such glass-based articles are also disclosed.
