Summary form only given. We present a quasi-analytical model for characterizing the output-field photon-statistics of nonlinear erbium-doped fiber amplifiers and amplifier-chains with arbitrary input-field statistics. All the available results on output-photon-statistics of linear amplifiers can be derived as a special case of the present nonlinear theory.

A parameteric study was performed of the sub-Poissonian photon statistics and higher-order squeezing characteristics of Bernouilli states undergoing a linear amplification process. The necessary and sufficient conditions on the amplifier gain under which the output light exhibits sub-Poissonian photon statistics or squeezing were compared with exact numerical results, and good agreement was obtained. On the other hand, it was shown that Bernouilli states exhibit higher-order squeezing for some parameter ranges. The degree of higher-order squeezing decreases, and its duration becomes shorter, as the phase of the Bernouilli state increases.
