Abstract

We have designed and fabricated sapphire-derived fiber with controllable core diameter using rod-in-tube method. The minimum core diameter could be 10 μm and due to the high alumina concentration and diffusion effect, the maximum refractive index difference of this sapphire-derived fiber (SDF) between core and cladding is up to 0.066. Because of the small core diameter and high alumina concentration, such SDF will be good candidate for high temperature and pressure environments applications.
