  • Abstract
    A three-dimensional index variation grating in bulk BGG31 glass written using neither hydrogen loading nor germanium doping is demonstrated. This material is useful for fabricating ion exchanged waveguides, and its photosensitivity to ultraviolet (UV) radiation at 248 nm has not been previously explored. Intensity measurements of the Bragg diffracted spots indicated a maximum index variation (Δn) of ~4×10-5
