Abstract
In some implementations, an optical fiber may include a core and a cladding surrounding the core. The core and the cladding may provide light guidance along the optical fiber in a light propagation direction. The core may have a taper in the light propagation direction in a section of the optical fiber. A diameter of the core may decrease independently of a diameter of the cladding in the section of the optical fiber.
Claims20
An optical fiber, comprising:
- a core;
- and
- a cladding surrounding the core, the core and the cladding providing light guidance along the optical fiber in a light propagation direction,
- wherein the core has a non-drawn taper in the light propagation direction in a section of the optical fiber,
- wherein a ratio of a diameter of the cladding to a diameter of the core is independent of a taper ratio of the core in the section of the optical fiber, and
- wherein a diameter of the core changes at a non-zero rate in the section of the optical fiber.

An optical fiber combiner, comprising:
- an enclosing tube;
- and
- a plurality of optical fibers bundled within the enclosing tube, wherein an optical fiber of the plurality of optical fibers comprises:
- a core;
- and
- a cladding surrounding the core, the core and the cladding providing light guidance along the optical fiber in a light propagation direction,
- wherein the core has a non-drawn taper in the light propagation direction in a section of the optical fiber,
- wherein a ratio of a diameter of the cladding to a diameter of the core is independent of a taper ratio of the core in the section of the optical fiber, and
- wherein a diameter of the core changes at a nonzero rate in the section of the optical fiber.

A method, comprising:
- obtaining an optical fiber comprising a core and a cladding surrounding the core, the core and the cladding providing light guidance along the optical fiber in a light propagation direction;
- and
- forming the core, in a section of the optical fiber, to have a taper in the light propagation direction,
- wherein a ratio of a diameter of the cladding to a diameter of the core is independent of a taper ratio of the core in the section of the optical fiber, and
- wherein a diameter of the core changes at a nonzero rate in the section of the optical fiber.
