An optical fiber may include a cladding structure extending along a fiber length providing a hollow interior fiber region, and anti-resonant (AR) elements formed as walled structures with walls extending along the fiber length. At least one of the AR elements surrounds an interior region and further includes one or more support structures in the interior region and formed as at least a portion of at least one of the walls, where the one or more support structures have a non-uniform thickness profile, and where the plurality AR elements is configured to guide light along the fiber length in a central portion of the hollow interior fiber region based on optical anti-resonance.

Anti-resonant hollow-core fibers featuring support structures

An optical fiber may include a cladding structure extending along a fiber length providing a hollow interior fiber region and one or more sets of anti-resonant (AR) elements formed as walled structures with walls extending along the fiber length. The one or more sets of AR elements may be distributed around an interior wall of the cladding structure and, configured to guide light along the fiber length in a central portion of the hollow interior fiber region based on optical anti-resonance. At least one of the one or more sets of AR elements may comprise a first AR element, two or more support structures disposed on an inner surface of the first AR element, and a second AR element disposed on at least one of the two or more support structures.

Fiber optic sensors based on multicore optical fibers that are intended for use in harsh environment sensing. This multicore fiber comprises an arrangement of optically coupled cores in a silica background. Sensors are fabricated by splicing a section of multicore fiber between two single mode fibers. This multicore fiber sensor is simple and repeatable to fabricate and multiple sensors can be multiplexed in a chain. These fiber optic sensors are intended for a broad set of sensing applications including temperature, pressure, strain, bending, acoustic vibrations, mechanical vibrations, or combinations thereof.
