1. An optical fiber comprising:
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, wherein the one or more sets of AR elements are distributed around an interior wall of the cladding structure, wherein the one or more 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, wherein at least one of the one or more sets of AR elements comprises:
a first AR element;
two or more support structures disposed on an inner surface of the first AR element, wherein the two or more support structures have non-uniform and solid thickness profiles in a cross-sectional plane orthogonal to the fiber length; and
a second AR element disposed exclusively on at least two of the two or more support structures and located within an interior region of the first AR element.
