A multicore optical fiber includes a cladding and multiple cores disposed in the cladding. Each core has a light-guiding path and follows a helical trajectory about a fiber axis. The multicore fiber also includes a set of discrete lateral coupling zones, which are longitudinally distributed and azimuthally aligned with respect to the fiber axis. Each lateral coupling zone forms an optical coupling path, which enables at least one of lateral in-coupling and out-coupling of light between a corresponding one of the cores and an exterior of the multicore fiber. An optical probing system for light delivery to and/or light collection from a probed region includes a multicore optical fiber to enable coupling of guided light out of the cores for delivery to the probed region and/or collection of light from the probed region for coupling into one of the cores.
A multicore optical fiber having a fiber axis, the multicore optical fiber comprising:
An optical probing system for at least one of light delivery to and light collection from a probed region, the optical probing system comprising a multicore optical fiber having a fiber axis and comprising a cladding, multiple cores disposed in the cladding and extending helically about the fiber axis, and a set of lateral coupling zones longitudinally distributed and azimuthally aligned with respect to the fiber axis, each one of the lateral coupling zones forming an optical coupling path enabling at least one of:
