In this paper, the probability of power depletion due to stimulated Raman scattering (SRS) is derived for an arbitrary number of interferers to estimate bit error rate and power penalty of a wavelength division multiplexed (WDM) receiver. Gaussian function approximation can be used only when the numbers of interferers is very large. The effects of number of interfering channels, channel separation and receiver noise on the bit error rate (BER) are studied. Minimum BER varies non-monotonically with channel separation. Optimum detection thresholds for minimum BER in the WDM receiver in presence of SRS crosstalk are investigated and summarized in tabular form. © 2006 IEEE.

Probability of Power Depletion in SRS Cross-Talk and Optimum Detection Threshold for Minimum BER in a WDM Receiver

IEEE Journal of Quantum Electronics

In this paper, optimum detection threshold for minimum bit error rate (BER) due to four-wave mixing is calculated taking the probability distribution of power depletion as binomial and considering nonuniform channel spacing. Nondegenerate four-wave mixing has been assumed for the worst-case analysis. The effects of the number of interfering channels, receiver noise, and input power on the BER in the presence of four-wave mixing are studied. The optimum detection threshold for minimum BER is studied as a function of the number of channels. This optimum threshold significantly deviates from the conventional threshold in the Gaussian distribution approximation as the channel number increases beyond three. © 2009-2012 OSA.

On the optimum detection threshold for minimum bit error rate due to four-wave mixing in a WDM system

In this paper, bit error rate and power penalty in a WDM receiver system in the presence of component crosstalk with finite interferers are studied using a simplified analysis and some optimum detection thresholds are suggested for minimum bit error rate. Error probabilities are calculated considering a unipolar bit stream of optical signals at the receiver input. Probability density function in the presence of crosstalk deviates from conventional Gaussian function. Effects of receiver noise, number of interfering channels and crosstalk levels on the receiver performance are shown. Optimum detection thresholds for minimum bit error rates in the WDM receiver in presence of component crosstalk are investigated and summarized in tabular form. © 2009 IEEE.
