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...
