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.
智能手机和平板电脑已无处不在。康宁®大猩猩®玻璃以其为众多智能手机及其他移动设备提供耐用性和抗刮性而闻名。我们首次报告了利用飞秒激光制作的高质量光子器件，如温度传感器和认证安全系统。研究发现，这种玻璃是三维波导的优异基质。据我们所知，采用飞秒激光写入技术，在任何玻璃中制作出了具有最低测量损耗值（0.027 dB/cm损耗）的高质量多模波导。还利用300 mm/s的飞秒激光扫描速度制作出了高质量（0.053 dB/cm损耗）的单模波导，这是迄今为止报道的最快制作速度。同时也报道了最长的高质量波导（长达1米）。实验表明，大猩猩玻璃似乎是在表面下方写入波导的理想玻璃，这在传感应用中具有重大意义。
