A study of UV absorption in germanosilicate fibre preforms
The strength of the 242 nm absorption band in MCVD germanosilicate fibre preforms is observed a) to be linearly dependent on Ge concentration and b) to increase by a factor of ~2.5 if O2 is replaced with He during the collapse process. It also reduces when the preform is co-doped with phosphorus, fluorine, aluminium and boron.

Abstract

The strength of the 242 nm absorption band in MCVD germanosilicate fibre preforms is observed a) to be linearly dependent on Ge concentration and b) to increase by a factor of ~2.5 if O2 is replaced with He during the collapse process. It also reduces when the preform is co-doped with phosphorus, fluorine, aluminium and boron.
