| Description |
A rare earth (RE) doped optical fiber is fabricated by depositing pure silicon dioxide (SiO 2 ) or phosphorus pentoxide-fluorine (P 2 O 5 -F) doped synthetic cladding within silica glass substrate tube to obtain matched or depressed clad type structure; forming core by depositing unsintered particulate layer; soaking tube containing porous soot layer into solution containing RE salt with barium; collapsing tube to obtain preform; jacketing preform with silica tubes of suitable dimensions; and drawing fibers from the preform, where barium oxide is used as codopant to control RE incorporation.
