Abstract
A method for producing a hollow-core preform may include rolling a glass sheet to form a rolled-glass structure; and attaching one or more of the rolled-glass structures to an inner surface of an annular support structure to form a hollow-core preform, wherein the inner surface of the annular support structure defines an interior cavity and the one or more of the rolled-glass structures are positioned within the interior cavity. The hollow-core preform may be drawn into a hollow-core optical fiber.
Claims20
A method for producing a hollow-core preform, the method comprising:
- rolling a glass sheet to form a rolled-glass structure;
- and
- attaching one or more of the rolled-glass structures to an inner surface of an annular support structure to form a hollow-core preform, wherein the inner surface of the annular support structure defines an interior cavity and the one or more of the rolled-glass structures are positioned within the interior cavity.
A method of forming a hollow-core optical fiber, the method comprising:
- drawing an optical fiber from a hollow-core optical fiber preform, the hollow-core optical fiber preform comprising:
- an annular support structure having an inner surface defining an interior cavity;
- and
- one or more rolled-glass structures attached to the inner surface and positioned within the interior cavity.
A hollow-core optical fiber comprising:
- a substrate, the substrate comprising a tubular shape and an inner surface surrounding a central longitudinal axis of the hollow-core optical fiber;
- a hollow core extending through the substrate along the central longitudinal axis of the hollow-core optical fiber;
- a cladding positioned between the central longitudinal axis of the hollow-core optical fiber and the substrate, the cladding comprising a rolled-glass cladding element circumscribing the central longitudinal axis, wherein the rolled-glass cladding element comprises a plurality of turns around the central longitudinal axis.
