Simultaneous amplification of C- and L-band signals using single double-clad two-core erbium-doped fiber
We propose a simultaneous C- and L-band amplification by using a single two-core double-clad erbium-doped fiber (EDF). The parameters of the two cores are optimized so that one core is used for C-band amplification and the other core is suitable for L-band amplification. Simulation results reveal that the two-core optical amplifier with the double-clad EDF has potential of over 20-dB gain in both C- and L-bands as well as the best cladding-pumping wavelength is in the 1480-nm band.
