Abstract
An optical fiber device may include a unitary core including a primary section and a secondary section, wherein at least a portion of the secondary section is offset from a center of the unitary core, wherein the unitary core twists about an optical axis of the optical fiber device along a length of the optical fiber device, and wherein a refractive index of the primary section is greater than a refractive index of the secondary section; and a cladding surrounding the unitary core.
Claims23
An optical fiber device, comprising:
- a unitary core including a primary section and a secondary section,
- wherein at least a portion of the secondary section is offset from a center of the unitary core,
- wherein the unitary core twists about an optical axis of the optical fiber device along a length of the optical fiber device, and
- wherein a refractive index of the primary section is greater than a refractive index of the secondary section;
- and
- a cladding surrounding the unitary core.

An optical fiber device, comprising:
- a unitary core including a primary section,
- wherein the primary section of the unitary core has a non-circular shape,
- wherein the unitary core twists about an optical axis of the optical fiber device along a length of the optical fiber device;
- and
- a cladding surrounding the unitary core.
2 more elements
A method, comprising:
- receiving, by a rotator fiber, an optical beam at a first end of the rotator fiber,
- wherein the rotator fiber includes a unitary core that twists about an optical axis of the rotator fiber along a length of the rotator fiber;
- at least partially converting, by the rotator fiber, the optical beam to a rotary optical beam,
- wherein the optical beam is at least partially converted to the rotary optical beam as a result of the unitary core being twisted about the optical axis;
- and
- outputting, by the rotator fiber, the rotary optical beam.
