摘要：
A double-pass erbium-doped fiber amplifier (EDFA) based on a depressed cladding erbium-doped fiber, which operates in the short wavelength (S-band) region is proposed and demonstrated. This amplifier provides a small signal gain as high as 30 dB at 1500 nm, using only 15 m depressed cladding erbium-doped fiber (EDF) and 130 mW of 980 urn pump power. Compared to the single-pass configuration, this amplifier shows a gain enhancement of about 14 dB for pump powers above 120 mW. However, noise figures penalties of less than 0.9 dB are obtained for these pump powers. The proposed double-pass amplifier will play an important role in the development of a practical S-band EDFA from the perspective of economical usage of EDF and pump power.
