In this paper, we review, first, the different noise terms involved in amplified and filtered spontaneous emission detection using the standard beating theory (or the semi-classical field expansion theory) of the noise in optical amplifiers. We derive BER calculations using the following approaches: 1) non-ideal electrical and optical filters combined with(More)
—In this paper, we evaluate the performances of a Direct-Sequence Optical Code Division Multiple Access (DS-OCDMA) system. We estimate the bit error rate (BER) of the system using Importance Sampling (IS) technique by taking into account multiple access interferences (MAI) and noises from the receiver. Conventional Monte-Carlo method uses a great number of(More)
—This paper reports for the first time an all-optical wavelength conversion of an incoherent optical signal to a coherent optical signal using the cross-gain modulation in semiconductor optical amplifiers. Wavelength division multiplexed networks using broadband sources have performance limited by beat noise; conversion from a non-coherent to a coherent(More)
In this paper, we demonstrate the importance of the number of wavelength division multiplexing (WDM) channels and the network traffic variability on the dynamics of a cascade of erbium-doped fibre amplifiers (EDFAs) fed by packet traffic in burst mode. The dynamics are determined using a numerical model incorporating time variation effects in the EDFA.(More)
