    Nonlinear refraction in rutile TiO2, at SPIE Photonics West: Nonlinear Frequency Generation and Conversion: Materials, Devices, and Applications XIII (San Francisco, California), Tuesday, February 4, 2014
    Titanium dioxide (TiO2) has attractive optical properties for nonlinear optical applications ranging from telecommunication to interconnect wavelengths (800–1600 nm). TiO2 demonstrates large linear and nonlinear refractive indices, wide transparency from the infrared to as low as 400 nm wavelengths, and low two-photon absorption for wavelengths longer than 800 nm. We use the Z-scan technique to investigate the nonlinear refraction and multiphoton absorption of bulk rutile TiO2 for wavelengths ranging from 800–1600 nm. Using our results, we calculate nonlinear figures of merit and discuss... Read more about Nonlinear refraction in rutile TiO2
