Paper Abstract

In a modern lightwave communication system, it is preferable to have a low dispersion penalty, long fiber span and a very high bit rate. There are many practical restrictions to achieve these targeted features. Consequently different approaches are available to optimise the operating conditions of the system. One of these limitations is the effect of the transit time in the photodiode on the performance of the whole receiver end that operates in multi-gigabit regime. Here in this paper we explore an approach to model the transit time within an optical receiver. This model used to formulate a moment generating function (mgf) which is later coupled within a Chernoff Upper Bound (CB) of the probability of error. Conditions are derived for reducing the effect of transit time, in the sense of minimising a CB for a Poisson channel. Firstly, a brief review of the role of the transit time on the speed of response of a photodiode is presented.
