题 目：Novel glass ceramic fibers for photonic devices
摘 要：Glass ceramic can be considered as a composite material exhibiting both excellent processing ability of glass and optical properties of crystal. However, there have been few investigations on fabrication of glass ceramic fibers up to now. The main reason may be due to the crystallization during fiber drawing process, resulting in large light scattering and optical attenuation. Here, we report a new technique called melt-in-tube method for fabrication of glass ceramic fibers with both low optical attenuation and optical properties. Different from traditional rod-in-tube method, the clad is softened while the core is melted during the fiber drawing, glass ceramic fibers are obtained by heat treatment of precursor fiber at lower temperature which allows one to precisely control the nucleation and crystallization. We will introduce various functional optical fibers such as glass ceramic fibers with tunable near infrared emission. second harmonic generation, and large third-order optical nonlinearity etc.
