HOLLOW-CORE OPTICAL FIBERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240036252 titled 'HOLLOW-CORE OPTICAL FIBERS

Simplified Explanation

The abstract describes a hollow-core optical fiber that consists of a hollow core, a substrate with an inner surface surrounding the core, and multiple cladding elements positioned between the core and the substrate. Each cladding element includes a primary capillary that directly contacts the substrate's inner surface and has a cavity, as well as nested capillaries positioned within the cavity that also directly contact the inner surface of the primary capillary.

The patent application describes a new type of hollow-core optical fiber.
The fiber has a hollow core extending along its central longitudinal axis.
It includes a substrate with a tubular shape and an inner surface surrounding the core.
Multiple cladding elements are positioned between the core and the substrate.
Each cladding element consists of a primary capillary that directly contacts the substrate's inner surface.
The primary capillary has a cavity.
Nested capillaries are positioned within the cavity of the primary capillary.
The nested capillaries also directly contact the inner surface of the primary capillary.
