Optical fiber elements for addressing individual cores in multicore optical fiber sensors

摘要

Multicore optical fibers gained a lot of interest in the different fields of fiber sensing. This is mainly due to the possibility of carrying out simultaneous measurements on each core and simplicity of such fiber fabrication. A disadvantage of multicore fibers is related to the complex introducing and detecting light from the individual cores. In this paper we discuss two classes of multicore fiber sensors and optical fiber elements for addressing individual cores in this kind of fibers.
