## Abstract A novel reflection Lβband erbiumβdoped fiber amplifier, based on a fiber loop mirror, is constructed. This amplifier reflects the backward ASE to the EDF as a secondary pumping source. A gain of 30 dB (an increase of 6 dB) is obtained, compared to the forwardβendβpumped EDFA in the rang
This paper provides keys to understand why erbium-doped fiber amplifiers (EDFA) have revolutionized signal transmission techniques and how they can complement with Raman amplification in the next generation of telecommunications systems. The basic physics of EDFAs is first reviewed, followed by a de
