Formation of Tm²⁺ ions in germanosilicate glass optical fibers

Kim, Yune-Hyoun / Paek, Un-Chul / Han, Won-Taek

For the first time, we have developed Tm²⁺-Tm³⁺ co-doped germanosilicate glass optical fibers by providing a strong reduction environment based on a solution doping technique in a modified chemical vapor deposition process. The incorporation of the Tm²⁺ ions into the fiber core was identified by a broad optical absorption band appearing from 350 to (similar to)900 nm, which was due to 4f-5d electronic transitions of the Tm ²⁺ ions. The electron paramagnetic resonance spectrum was also measured to confirm the formation of the Tm²⁺ ions in the fiber preform by addition of a reducing agent during the preform preparation. The concentration of the Tm²⁺ ions in the fiber core was found to increase with the increase of heat treatment temperature just after drying the soaked porous core layers.
