    Abstract: The present disclosure is directed to a doped silica-titania glass, DST glass, consisting essentially of 0.1 wt. % to 5 wt. % halogen, 50 ppm-wt. to 6 wt. % one or more oxides of Al, Ta and Nb, 3 wt. % to 10 wt. % TiO2 and the remainder SiO2. In an embodiment the halogen content can be in the range of 0.2 wt. % to 3 wt. % along with 50 ppm-wt. to 6 wt. % one or more oxides of Al, Ta and Nb, 3 wt. % to 10 wt. % TiO2 and the remainder SiO2. In an embodiment the DST glass has an OH concentration of less than 100 ppm. In another embodiment the OH concentration is less than 50 ppm. The DST glass has a fictive temperature Tf of less than 875° C. In an embodiment Tf is less than 825° C. In another embodiment Tf is less than 775° C.
