An enhanced triple-pass hybrid optical fiber amplifier in a dual-stage configuration is presented by utilizing a combination of hafnium-bismuth erbium-doped fiber (HB-EDF) and bismuth erbium-doped fiber (Bi-EDF) as gain medium. The total Erbium-doped fiber length was only 199 cm, and both HB-EDF and...
