Refractivity of P<sub>2</sub>O<sub>5</sub>-Al<sub>2</sub>O<sub>3</sub>-SiO<sub>2</sub> Glass in Optical Fibers
A significant change in the refractive index profiles for the large mode area phosphoroaluminosilicate (PAS) core optical fibers was observed in comparison to that in preforms. This study shows that the refractive index of the PAS core can vary from negative (in preform) to positive (in fiber), and...

| description | A significant change in the refractive index profiles for the large mode area phosphoroaluminosilicate (PAS) core optical fibers was observed in comparison to that in preforms. This study shows that the refractive index of the PAS core can vary from negative (in preform) to positive (in fiber), and the difference in the refractive index between the core and preform can exceed a few thousand. By measuring a large set of fibers with different concentrations of P<sub>2</sub>O<sub>5</sub> and Al<sub>2</sub>O<sub>3</sub>, we define the refractivity of each dopant (P<sub>2</sub>O<sub>5</sub>, Al<sub>2</sub>O<sub>3</sub> and AlPO<sub>4</sub> joint) after drawing fiber from the preform and discuss the possible origin of the observed refractive index variation. |
