ABSTRACT:
A hybrid pumping scheme for rare-earth doped fiber amplifiers is disclosed. In particular, the arrangement utilizes at least two pump sources, operating at different wavelengths, coupled to a section of doped optical fiber, such as erbium-doped optical fiber. Optical multiplexers, such as fused fiber couplers, may be used to couple the message signal desired to be amplified, as well as the pump sources, to the doped fiber section. For certain embodiments, the doped fiber may be segmented into separate components, with the length of each component determined with respect to the wavelength of the associated pump signal.
