The degradation of fiber modes due to bending suggests the parabolic profile as an interesting
candidate for large-mode-area applications. A quadratic index profile has the property that its
shape and curvature are preserved under the fiber-bend transformation, which should allow
parabolic profiles to maintain higher effective area and better mode shape in the presence of
realistic bends. We present encouraging simulation results for examples of parabolic-profile
fibers, displaying reduced distortion and contraction of the mode.
