Abstract
An anti-resonant hollow-core fiber comprising a first tubular, cladding element which defines an internal cladding surface, a plurality of second tubular elements which are attached to the cladding surface and together define a core with an effective radius, the second tubular elements being arranged in spaced relation and adjacent ones of the second tubular elements having a spacing therebetween, and a plurality of third tubular elements, each nested within a respective one of the second tubular elements.

An anti-resonant hollow-core fiber comprising:
- a first tubular element having an internal cladding surface,
- a plurality of second tubular elements attached to the internal cladding surface, the plurality of second tubular elements being arranged about the internal cladding surface such that adjacent ones of the plurality of second tubular elements are spaced apart from each other;
- a plurality of third tubular elements, each nested within a respective one of the plurality of second tubular elements;
- and
- a plurality of fourth tubular elements, each nested within a respective one of the plurality of third tubular elements.
A hollow-core fiber, comprising:
- a first tubular element having an internal cladding surface;
- a plurality of nested tubular arrangements each attached to the internal cladding surface and spaced apart from one another, wherein each of the plurality of nested tubular arrangements comprises:
- a second tubular element attached to the internal cladding surface;
- a third tubular element nested within the second tubular element;
- and
- a fourth tubular element nested within the third tubular element.
An anti-resonant hollow-core fiber, comprising:
- a first tubular element having an internal cladding surface;
- a plurality of second tubular elements attached to the internal cladding surface, the plurality of second tubular elements being arranged about the internal cladding surface such that adjacent ones of the plurality of second tubular elements are spaced apart from each other and collectively define a core of the first tubular cladding element;
- a plurality of third tubular elements, each nested within a respective one of the plurality of second tubular elements;
- and
- a plurality of fourth tubular elements wherein each of the plurality of fourth tubular elements is attached to the respective one of the plurality of third tubular elements.
