Abstract
An optical fiber has a core with a diameter dc and a reflective index nc; a primary cladding concentrically surrounding the core and having an outer diameter dpc and a refractive index npc less than the core refractive index nc; and a secondary cladding concentrically surrounding the primary cladding and having an outer diameter dsc and a refractive index nsc less than the primary cladding refractive index npc.
