Refractive Index of Aluminophosphosilicate Glass in Optical Fibers near AlPO4 Join
The minimum refractive index of the aluminophosphosilicate (APS) core in optical fibers has been determined for a wide range of phosphorous and aluminum concentrations. It was found that the APS core refractive index became higher by ~0.0005–0.0012 as compared to that in optical fiber preform. The analysis of the measured data has shown that at least 0.2 mol.% of Al2O3 and P2O5 remain in their ordinary form near their equimolar concentrations and do not form an AlPO4 join (the effect observed for all concentrations of AlPO4 join from 5 to 25 mol.%).
