Multiple soaking with different solution concentration in doped silica preform fabrication using modified chemical vapor deposition and solution doping

Incorporation of alumina (Al2O3) into a silica matrix by modified chemical vapor deposition and a solution doping technique is investigated in this study. Multiple soaking cycles were used to increase the aluminum content in the core layer. The effect of alumina retention in silica matrix soot is fo...
