Abstract
An anti-resonant hollow-core optical fiber includes an outer cladding; a holding tube; a first plurality of cladding elements arranged within the outer cladding; and a second plurality of cladding elements arranged in contact with an inner wall of the holding tube, such that the second plurality of cladding elements define a hollow core, wherein a first wall thickness of the second plurality of cladding elements causes a first anti-resonant condition for the hollow core and a sum of a holding tube wall thickness and a wall thickness of first plurality of cladding elements causes a second anti-resonant condition for the hollow core.

An anti-resonant hollow-core optical fiber, comprising:
- an outer cladding;
- a holding tube;
- a first plurality of cladding elements arranged within the outer cladding;
- and
- a second plurality of cladding elements arranged in contact with an inner wall of the holding tube, such that the second plurality of cladding elements define a hollow core,
- wherein a first wall thickness of the second plurality of cladding elements causes a first anti-resonant condition for the hollow core and a sum of a holding tube wall thickness and a wall thickness of first plurality of cladding elements causes a second anti-resonant condition for the hollow core.
An anti-resonant hollow-core optical fiber, comprising:
- an exterior cladding;
- a first layer disposed within the exterior cladding and defining a first inner volume,
- wherein the first layer includes a first set of cladding elements;
- a second layer disposed within the first layer and defining a second inner volume,
- wherein the second layer includes a second set of cladding elements,
- wherein the second set of cladding elements defines a hollow core;
- and
- a holding tube disposed between the first layer and the second layer,
- wherein a configuration of the first set of cladding elements, the second set of cladding elements, and the holding tube is associated with reducing a loss of a fundamental mode associated with the hollow core.
A layered hollow-core optical fiber, comprising:
- a first plurality of cladding elements disposed in a first interior volume;
- a second plurality of cladding elements disposed in a second interior volume;
- and
- a holding tube disposed between the first interior volume and the second interior volume,
- wherein the second plurality of cladding elements define a hollow core, and
- wherein respective wall thicknesses of the first plurality of cladding elements, the second plurality of cladding elements, and the holding tube are configured to cause an anti-resonant condition for the hollow core.
