Broadband fiber lasers using bismuth-oxide-based erbium-doped fiber amplifiers

Bismuth oxide-based erbium-doped fiber amplifiers (Bi-EDFAs) are attractive because of their broad gain bandwidth and high gain per unit length. In this paper, several applications of broadband bismuth oxide-based erbium-doped fiber lasers (Bi-EDFLs) are reviewed including a wideband tunable single frequency Bi-EDFL, a femtosecond passively mode-locked Bi-EDFL, and applications to broadband spectrum generation.
