LOW LOSS OPTICAL FIBER AND METHOD OF MAKING THE SAME

The core region of an optical fiber is doped with chlorine in a concentration that allows for the viscosity of the core region to be lowered approaching the viscosity of the surrounding cladding. An annular interface region is disposed between the core and cladding and contains a concentration of fl...

description	The core region of an optical fiber is doped with chlorine in a concentration that allows for the viscosity of the core region to be lowered approaching the viscosity of the surrounding cladding. An annular interface region is disposed between the core and cladding and contains a concentration of fluorine dopant sufficient to match the viscosity of the core. By including this annular stress accommodation region, the cladding layer can be formed to include the relatively high concentration of fluorine required to provide the desired degree of optical signal confinement (i.e., forming a low loss optical fiber).
