Linear-core-array microstructured fibers are fabricated using the modified chemical-vapor desposition and etching method for preparing each core performs, and two D-shape large-scale silica rods are also used in the linear-core-array fiber perform stacking. The supermodes in optical fibers with linearly distributed 23 cores are investigated by using the coupled-mode theory. The coupling field propagation characteristics of the optical fibers are analyzed. The linear-core-array fiber could be used in improving the high-power fiber laserbeam shape, enhancing its quality.
