Abstract
An optical fiber may include a first core, a second core, and a cladding surrounding the first core and the second core. The second core may be at an off-center location with respect to a center of the optical fiber, or the second core may include an azimuthally nonuniform section at the off-center location. The second core may twist about an axis of the optical fiber along a length of the optical fiber, and the second core being twisted about the axis may cause an optical beam, launched into the second core at a first end of the optical fiber, to be at least partially converted to a rotary optical beam at a second end of the optical fiber.
