High efficiency broad bandwidth erbium-doped superfluorescent fiber source Download: 792次
Abstract
A practical two-stage double-pass structure using high concentration erbium-doped fiber and 1480-nm pump laser diode is suggested for a high power and broad bandwidth erbium-doped superfluorcscent fiber source. A considerable increase in output power and bandwidth extension is achieved by adding an unpumped fiber and a broadband fiber mirror to make the most of wasted backward amplified spontaneous emission as both pump and input light source simultaneously. Superfluorcscent fiber source with nearly 80-nm bandwidth and 28.6-mW output power is obtained experimentally.
