ABSTRACT:
A large mode area (LMA) fiber with improved resistance to bend-induced distortions utilizes highly oscillatory modes such that the effective index of the propagating modes remains less than the bent-fiber “equivalent” refractive index over a greater portion of the core. By providing a signal mode with a reduced effective index, the “forbidden” (evanescent) region of the core is reduced, and bend-induced distortion of the propagating mode is largely avoided.
