Abstract
An optical fiber system comprises an optical fiber having a doped core and a first cladding about the doped core. The optical fiber has a first longitudinal portion and a second longitudinal portion, and is arranged such that the first longitudinal portion and the second longitudinal portion are longitudinally side by side. The first cladding of the first longitudinal portion is adjacent to the first cladding of the second longitudinal portion such that light propagating in the first cladding can move laterally from the first longitudinal portion to the second longitudinal portion to increase the amount of light reaching the doped core. The optical fiber is adapted to be coupled to a power input and has an output end for outputting light emitted by the doped core. The second fractional cladding about the first cladding conceals light in the first cladding.
