Abstract
A fiber-based optical amplifier is formed to exhibit a reflective architecture in a particular configuration where a single pump source is shared among several individual reflective amplifier elements. A passive, non-variable power splitter is used to direct sub-beams of sufficient power into the rare-earth doped fiber contained within individual amplifiers. Since the reflective architecture results in an optical signal passing through the doped fiber coil (gain medium) twice, a lower pump power (compared to a conventional single-pass structure) may be used to obtain the same target output power level and the single pump source is considered as sufficient to provide enough output power to pass through a power splitting arrangement and deliver enough pump power to provide amplification of a propagating optical signal in each of the individual amplifiers.
