Paper Abstract

We investigate hybrid erbium-doped fiber amplifiers (EDFAs) for use as broadband sources of amplified spontaneous emission (ASE) in spectrum-sliced wavelength-division multiplexed (WDM) networks. We report experimental results of two-stage, i.e., two-fiber sources that demonstrate the potential of hybrid EDFAs as high-power, broadband sources with high spectral uniformity. We have developed a numerical model in order to optimize the design of such sources. The model provides for use of multiple fibers and incorporation of optical filters. We present a preliminary theoretical design, derived using the model, of a high-power, broadband source that incorporates three fibers and two filters. The theoretical output spectrum of the source is a uniform comb of wavelength channels ideally suited for use in spectrum- sliced WDM networks. The output spectrum has 19 channels within a 3 dB bandwidth with 2 nm spacing and an average per-channel power of 1.0 mW.
