Abstract
An all-glass cladding mode stripper comprises a plurality of high refractive index, small diameter glass beads disposed along an exposed portion of the inner cladding region of an optical fiber. The unwanted low NA signal light (as well as any other type of stray light) propagating within the cladding layer is removed by refracting into the adjacent beads, where this captured light then scatters away from the optical fiber.
