Characteristics of 1.48um Pumped Erbium-Doped Fiber Amplifier with High Efficiency,

Abstract

Erbium-doped fiber amplifiers(EDFAs) are very attractive devices for single-mode fiber communication systems operating In the 1.55 p m wavelength band. (1) The main advantages of EDFAs are polarization-Insensitive high gain, high amplification efficiency, low Insertion loss, low noise and wide bandwidth. (2) There are two Important parameters to evaluate EDFA's performance; an energy conversion efficiency and a gain coefficient. In this paper, we report an extremely high efficiency EDFA with a slope efficiency of 86% and a gain coefficient of 6.3dB/mW at 1.48 p m by increasing the numerical aperture(NA) of the erbium-doped fiber and concentrating the dope Er3+ Ions near the center of the core. (3) (4) Both are the highest values reported to-date for EDFAs pumped at 1.48 um.
