Abstract

Between core and cladding, the side-emitting step index fibers have scattering centers that ensure the coupling out of light from the fiber. The side-emitting step index fibers are produced by preforms that contain inlay rods, in which the scattering centers are embedded and which are applied to the outer region of the fiber core during fiber drawing. Alternatively, at least one inlay tube can be used.
