Abstract
An article includes a glass ceramic that has an amorphous silicate glass phase and a crystalline phase including a species of MxWO3 with 0<x<1 and M an intercalated dopant cation. The article further includes an aperture configured to be formed via local heating of a portion of the glass ceramic to a temperature that is above the softening point of the glass ceramic. The aperture comprises constituents of the silicate glass phase and the crystalline phase but is substantially free of the species of MxWO3. A ratio of a transmittance of the aperture to a transmittance of the glass ceramic not subject to the local heating is at least 6,000 with transmittance measured in %/mm at wavelengths from 500 nm to 1100 nm.
