Refractive Index of Aluminophosphosilicate Glass in Optical Fibers near AlPO<sub>4</sub> 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 a...

| Summary: | 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 Al<sub>2</sub>O<sub>3</sub> and P<sub>2</sub>O<sub>5</sub> remain in their ordinary form near their equimolar concentrations and do not form an AlPO<sub>4</sub> join (the effect observed for all concentrations of AlPO<sub>4</sub> join from 5 to 25 mol.%). |
