Amplification by white light-emitting diode pumping of large-core Er-doped fiber with 12 dB gain

Abstract

We have developed a cost-effective, high-capacity Er-doped fiber amplifier based on the high-power white LED and a large-core Er-doped fiber. Er ions of the fiber with absorption bands at 453, 488, 523, and 654 nm were simultaneously excited by LED pumping and amplification with optical gain over 12 dB at 1550 nm was obtained.
