【 摘 要 】

In this paper, we fabricated the crystalline germanium core silica cladding fiber with rod-in-tube method. Its strain distribution inside the fiber was analysed using Raman spectroscopy. The results reveal that the core of the prepared fiber has relatively high degree of crystallization and a relatively uniform strain distribution inside the germanium core.
