A technique for significantly increasing the pump power in an erbium doped fiber amplifier by multiplexing pump lasers at different wavelengths is demonstrated. Two pump lasers with a wavelength separation of at least 10 nm are combined with an inser

Recent development of low-loss, Er-doped silica fibers has made deployment of optical amplifiers in today's optical communication networks a reality. Among several techniques used for fabricating rare-earth doped fibers, the solution-doping technique

Pumping erbium-doped fiber amplifiers (EDFAs) near 980 nm has attracted much attention as a result of the lower noise characteristics and higher pump efficiency achieved compared to those obtained at 1480nm. The narrow absorption profile of the fiber

Pumping erbium-doped fiber amplifiers (EDFAs) at 980 nm provides the best overall performance achievable. However, it is a relatively narrow band and the constraints this imposes on pump laser wavelength have been sources of continuing concern [1,2].

The mechanical performance of fusion splices is quite sensitive to splicing equipment and practices. We observed degradation in fiber strength during fusion splicing by examining effects of splicing practices, fiber types and environmental conditions

Despite the excellent performance that has been demonstrated for Er 3+ -doped fiber amplifiers at 1.5 µ m, they have several shortcomings that remain concerns in practical applications. The efficiency, gain, and signal/noise ratio of three-level dev
