Abstract

A hybrid double cladding EYDFA with SMS structure is proposed and theoretically analyzed. The hybrid gain fiber with SMS structure is composed of two kinds of EYDFs with different core diameter. The output power performance and output spectra of the amplifier with hybrid gain fiber are numerical analyzed, and are compared with that of the amplifier with uniform gain fiber. The simulation results demonstrate that this fiber amplifier with SMS structure gain fiber can suppress the Yb-ASE by over 10 dB without output power reduction. It provides a monolithic structure for EYDFA to overcome pump bottleneck effect and achieve high efficiency and high power output.
