Temperature and dopant concentration in single-mode 5-um diameter optical fiber--cooling through the die: implications for Laguerre orders in optical refractive synchronization

摘要

The object of this paper is to evalute both the temperature distribution and the dopant concentration for a 5 micron diameter single mode SiO$-2$/ fiber optic that is doped with GeO$-2$/. Fundamentally, what drives the need to know this information springs from a theoretical model which suggest that the index of refraction, leading from the center to the edge, follows a parabolic curve.
