Abstract

A new method for direct writing of localized, circularly symmetric refractive-index changes in optical fibers with
a femtosecond laser is demonstrated. The refractive-index changes are characterized using a novel approach
employing comparison of numerical simulations to the measured far-field profiles of unmodified and modified
fibers. From the analysis, a negative refractive-index change of −0.015 0.005 within a radius of 0.6 0.1 μm
is determined.
