Abstract :
Broadband fluorescence enhancement in Cr-doped fibers (CDFs) fabricated by drawing-tower integrated powder-in-tube with redrawing technique is proposed and demonstrated. The CDFs after heat treatment exhibited Cr+4 emission enhancement with spectral density of 200 pW/nm which was identified as the formation of α-Mg2SiO4 nanocrystalline structures in the core, observed by HRTEM.
