Strict calculation of the light statistics at the output of a travelling wave optical amplifier

A new method for calculating the probability density function of the photon number propagating through a travelling wave optical amplifier with no restriction on its working regime (linear and nonlinear) is reported. The authors show that the widely used Gaussian approximation of the probability density function does not match the real statistics if the incident optical power is small.Peer ReviewedPostprint (published version

Practical method for modelling the nonlinear behaviour of a travelling wave semiconductor optical amplifier

The authors present a simple model of a travelling wave semiconductor optical amplifier with an appreciable degree of saturation. The model uses a particular way of linearising the total carrier recombination R(N) to find useful expressions for the saturation parameter and/or the carrier lifetime. By combining these expressions and the gain measurements realised, it is possible to establish the dependence between the mentioned parameters and the input optical power.Peer ReviewedPostprint (published version

Caracterización experimental de un amplificador optico de fibra dopada ER3+: Presentaciones en sistemas de transmisión coherente

In this communication we present an experimental characterization of an Er3+ -doped fiber amplifier. This kind of amplifier shows high gain and large bandwidth that can be very useful in improving performances of wide band coherent transmission systems . The resul ts obtained al so show good agreement with simulations of the theoretical model we have developed.Peer ReviewedPostprint (published version
