Smart phones and tablets have become ubiquitous. Corning® Gorilla® Glass is well-known to provide durability and scratch-resistance to many smart phones and other mobile devices. Using femtosecond lasers, we report high quality photonic devices, such as a temperature sensor and an authentication security system, we believe for the first time. It was found that this kind of glass is an exceptional host for three dimensional waveguides. High quality multimode waveguides are demonstrated with the lowest measured loss value (0.027 dB/cm loss) to our knowledge in any glass using fs laser inscription. High quality (0.053 dB/cm loss) single-mode waveguides have been also fabricated using a fs laser scan speed of 300 mm/s, the fastest fabrication speed reported to date. The longest high quality waveguides (up to 1m) are also reported. Experiments reveal that Gorilla Glass seems to be an ideal glass to write waveguides just below the surface, which is of great interest in sensing applications.
