摘要：A method of making an optical fiber article can include providing an optical fiberincluding at least a core; providing a preform; and subsequent to the foregoing providingof the optical fiber and the preform, drawing the preform so as to dispose a region aboutthe optical fiber. An optical fiber article can include a core; a pump cladding disposed
about the core, the pump cladding for propagating pump light; and a second claddingdisposed about the pump cladding, where the second cladding can provide a photonicbandgap for tending to confine pump light to a region about which the second claddingis disposed. The second cladding can comprise a plurality of layers including a first layerhaving a different optical property than a second layer, and the plurality of layers can bearranged as to provide the photonic bandgap effect.
