Abstract

We fabricated a new type of multicore fiber using the PCVD process and stack-and-draw method. The fabrication process is described in detail in this work. The fiber core is composed with 91 GeO2-doped micro-rods arranged in the hexagon shape and the largest core diameter of the fabricated fibers is measured up to 50μm, very suitable for low loss splicing with the multimode fiber. For the fiber with 125μm glass diameter, the attenuation is measured only 3dB/km at 1060nm and lower than 10dB/km at 1550nm, the water-loss peak at 1383nm is about 110dB/km; the mode properties of our fiber were also measured, which show the fundamental mode characteristic with good Gaussian configuration. The large single mode area can deduce the nonlinear effect in the high power delivery. Our multicore fiber might have the potential application such as the delivery of high power, the multiparameter fiber sensor, etc. according to our design.
