Abstract
An apparatus for scattering light may include: an optical fiber having a first length; and a sleeve, having a second length shorter than the first length, around the optical fiber. The optical fiber may include: a core; and cladding around the core. The sleeve may include fiber-optic material. The fiber-optic material may be substantially polymer-free. An outer surface of the sleeve may be roughened to scatter the light out of the sleeve through the roughened surface. A method of forming an apparatus for scattering light may include: providing a sleeve having a first length, the sleeve having inner and outer surfaces; providing an optical fiber having a second length longer than the first length; passing the sleeve around the optical fiber or threading the optical fiber through the sleeve; and roughening at least a portion of the outer surface of the sleeve.
