17 September 1999 Holographic deposition of gratings in glass

High-resolution holographic gratings have been prepared in glass by photodeposition of iron oxide, principally Fe2O3, in Si-based porous glasses followed by thermal consolidation to a nonporous glass. A comparison of the properties of the holographically prepared gratings with those produced by direct laser writing in similar glasses show a significant improvements in the uniformity of the deposited gratings and their optical performance.
