— The error performance of a preamplified, direct detection receiver with an optical filter of the Lorentzian type is studied. The analysis takes into account the influence of the optical intersymbol interference (ISI). A closed-form expression of the moment generating function (MGF) of the decision variable is derived. Error probabilities are evaluated(More)
— Internet Protocol layer multicast by means of electronic processing is going to be the bottleneck of the next generation optical networks. Optical routers with optical layer multicast capability will become the new focus to overcome the speed limit and simplify the logical network stack structure. In this paper, optical multicast technologies by(More)
An eecient method for evaluating the error probability of optical ASK/DD systems subject to interferometric noise is presented. The receiver decision variable is statistically described by its moment generating function (mgf). The theoretical results, obtained with the aid of the new derived mgf, are in good agreement with experiment, employing directly(More)
We present the approach of cognition applied to heterogeneous optical networks developed in the framework of the EU project CHRON: Cognitive Heterogeneous Reconfigurable Optical Network. We introduce and discuss in particular the technologies and techniques that will enable a cognitive optical network to observe, act, learn and optimizes its performance,(More)
—In this paper, we present a recursive formula for the moments of phase noise in communication systems. The phase noise is modeled using continuous Brownian motion. The recursion is simple and valid for an arbitrary initial phase value. The moments obtained by the recursion are used to calculate approximations to the probability density function of the(More)
