Paper Abstract

In this paper, a practical two-stage scheme is suggested for generating a C+L-band erbium-doped fiber amplified spontaneous emission (ASE) broadband light source. A considerable power increase of the L-band ASE spectrum is achieved by injecting the C-band ASE into the long section erbium-doped fiber. The C+L-band ASE source is obtained by combining the enhanced L-band ASE with the C-band ASE from two stages respectively. A spectrum flat ASE source with nearly 80nm bandwidth and about 15.9dBm output power is obtained with a total pump power of 180mW. Namely, the pump conversion efficiency is about 21.6%. Such a broadband incoherent light source is desirable for various applications in some areas like sliced wavelength- division multiplexed local-access networks, characteristic measurement for dense wavelength-division multiplexed components, and fiber-optic sensor systems etc.
