Abstract

A Gaussian Noise Model of the nonlinear noise power spectral density is developed for a semiconductor optical amplifier as described by the Agrawal model. A simple closed-form expression is obtained for the nonlinear noise-to-signal ratio of broadband wavelength-division multiplexed signals as a function of the Agrawal model parameters, the amplifier output power and the transmission bandwidth. The accuracy of the closed-form expression and its region of validity is assessed in numerical simulations. The error is smaller than 0.1 dB when the product of bandwidth and gain recovery time B×τ_c exceeds 100.
