Weak coupling bridge for optical fiber cores

A bridge for weakly coupling optical cores in a multicore fiber. An inner cladding surrounds each of the cores. A plurality of bridges laterally connects each of the cores to adjacent cores. The bridges run the length of the fiber. Each bridge enhances the weak evanescent coupling between the cores...

Summary:A bridge for weakly coupling optical cores in a multicore fiber. An inner cladding surrounds each of the cores. A plurality of bridges laterally connects each of the cores to adjacent cores. The bridges run the length of the fiber. Each bridge enhances the weak evanescent coupling between the cores for frequencies of the light being transmitted by the fiber that are smaller than a cut-off frequency. This permits increased spacing of the cores. This abstract is provided to comply with the rules requiring an abstract, and is intended to allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
