Abstract

In this paper, we present a comprehensive mathematical model for the novel double cladding fiber, based on the rate and propagation equations, the output signal power and noise characteristics of double-cladding erbium-ytterbium co-doped fiber amplifiers with a reflector are analyzed numerically. Due to the contributions of the reflector to reflect the un-absorbed pump power, pump light transmitted in the active fiber is increased and the output performances are improved, it is shown that the amplifiers with the reflector have about the same high-power output signal as those without it, only using half-lengths of fiber. The pumping scheme and numerical results could be useful for the real optimized design of DCF amplifier in the near future.
