Spectrum sliced C+L-band multi-wavelength fiber source

A scheme for generating multi-wavelength fiber source based on erbium-doped fiber amplified spontaneous emission and spectrum sliced technique is demonstrated for potential applications in the dense-wavelength division multiplexing (DWDM) communication systems. A spectrum sliced multi-wavelength fiber source of 140 channels (extinction ratios larger than 13 dB) with 0.57nm channel spacing covering C-band and L-band is obtained by optimizing the erbium-doped fiber length and the pumping ratio of the scheme.
