Abstract

We have used the photorefractive two-beam-coupling technique to measure the nonlinear coefficient (n2/Aeff) of several telecommunication fibers and investigated the dependence of n2/Aeff on Er, Al, and Ge doping profiles in single-mode fibers, where n2 is the nonlinear refractive index and Aeff is the effective area of the LP01 mode. A semiempirical relation is derived for predicting the value of n2/Aeff as a function of Er, Al, and Ge content in optical fibers. We have further examined the wavelength dependence of Aeff in pure and doped silica fibers between 1064 and 1552 nm and found that the Aff value of doped fibers changes more markedly with wavelength than, that of pure-silica fibers. © 2005 Optical Society of America.
