Abstract
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.
Claims17
An optical fiber comprising:
- a cladding structure extending along a fiber length providing a hollow interior fiber region;
- and
- a plurality of anti-resonant (AR) elements formed as walled structures with walls extending along the fiber length, wherein the plurality of 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, wherein the plurality of AR elements includes at least one nested set of AR elements comprising:
- a first AR element formed as a wall extending along the fiber length and located entirely within the hollow interior fiber region, wherein the wall of the first AR element, in a cross-sectional plane orthogonal to the fiber length, fully surrounds an interior region and further has a non-uniform thickness profile between the first interior region and an outer perimeter of the first AR element, wherein the non-uniform thickness profile forms a support structure with a solid shape in the cross-sectional plane;
- and
- a second AR element located within the interior region of the first AR element and exclusively in contact with the support structure.
An optical fiber comprising:
- a cladding structure extending along a fiber length providing a hollow interior fiber region;
- and
- one or more nested sets of anti-resonant (AR) elements formed as walled structures with walls extending along the fiber length, wherein a particular one of the one or more nested sets of AR elements comprises:
- a first AR element formed as a wall extending along the fiber length and located entirely within the hollow interior fiber region, wherein the wall of the first AR element, in a cross-sectional plane orthogonal to the fiber length, fully surrounds an interior region;
- and
- a second AR element within the interior region of the first AR element, wherein the second AR element is exclusively coupled with a slab support structure and positioned with the interior region by the slab support structure, wherein the slab support structure has a non-uniform thickness profile, wherein the one or more nested sets of AR elements are configured to guide light along the fiber length in a central portion of the hollow interior fiber region based on optical anti-resonance.
