    摘要： A multicore collimator collimates light signals transmitted by respective cores of a multicore fiber. An array of gradient-index lens includes a plurality of individual gradient- index lenses corresponding to respective cores of the multicore fiber. The plurality of gradient-index lenses extends through a lens array body between an input end and an output end thereof and has a lens-to-lens spacing that is larger than the core-to-core spacing of the multicore fiber. A taper at the input end of the array of gradient-index lenses provides a tapered transition between the core-to-core spacing of the multicore fiber and the lens-to-lens spacing of the array of gradient-index lenses. The array of gradient-index lenses is configured to collimate the light signals outputs from the coupler, and to provide the collimated light signals as an output at the output end of the array of gradient-index lenses.

    摘要： A multicore fiber comprises a plurality of cores extending along the length of a fiber body. Each of the cores is surrounded by a cladding. The plurality of cores and surrounding cladding provide respective index variations, so as to form a. respective plurality of waveguides for conducting parallel data transmissions from a first end of the fiber to a second end. The plurality of cores has a cross-sectional geometry in which the plurality of cores is configured in a polygonal array, in which at least some of the cores are positioned at the vertices of the array. The polygonal array is configured such that neighboring cores in the array are separated from each other by a distance that Is sufficient to prevent crosstalk therebetween.
