Abstract

Nonlinear optical glasses with fast responding nonlinearities and very low absorption are promising materials for use in ultra-fast (picosecond) all-optical switches. We have synthesized a TiO2 Nb2O5. B2O3 Na2O SiO2 glass with the intention of optimizing both the third order optical nonlinearity and suitability for fabrication of optical waveguides. The nonlinear index coefficient n2 for this glass composition was found to be 4X 10-19 m2/W, a factor of two greater than the largest value previously reported for commercially available TiO2-silicate glasses. Optical waveguides with a maximum index change of Δn = 0.12 were made using silver-sodium ion exchange. These waveguides may become building blocks for future all-optical logic elements and circuits.
