Abstract

Interferometric crosstalk due to imperfect component performance has been shown to have a dramatic impact on performance in optical networks. In this paper we assess the impact of incoherent interferometric crosstalk in terms of BER and power penalty (PP). We use a rigorous formulation based on the modified Chernoff bound (MCB) which provides an accurate upper bound on the BER and on the PP. We compare these results with the Gaussian approximation (GA) and identify the scenario for which the GA can be applied with confidence. The influence of the decision threshold level is also examined and we will show that optimisation of the threshold can provide up to about 5 dB of crosstalk isolation.
