Rare-earth (RE) ions such as Nd3+, Er3+, and Yb3+ function as the basis of optical wave-guide amplifiers by emitting photons when electronic transitions are stimulated by incoming light. The conversion efficiency between stimulating light and emitted light, however, can be hampered by many factors, such as interactions between implanted ions and the embedding matrix, or if RE ions are not homogeneously distributed within the host material, they may be subject to non-radiative decays and will not function as needed. Implantation of rare-earth (RE) ions into porous oxide glasses will provide a most effective fabrication approach for active planar optical waveguides with enhanced performance. Processing materials under non-equilibrium conditions allows us to exceed solubility limits and prevents clustering of RE ions. Given the non-uniform pore size distribution in xerogels, it is also possible that larger RE penetration depth can be achieved upon implantation. |
