摘要
An S-band erbium-doped fiber (EDF) amplifier based on a W-type EDF designed by ourselves is demonstrated by employing a two-stage double-pass configuration. The amplifier provides a bandwidth of 34nm (1486-1520 nm) for the gain over 20 dB. The maximal gain of 32.8 dB is achieved at 1501nm and the corresponding noise figure is 6.0 dB. The proposed amplifier has a promising foreground in extending the current network to the S band.
