Optical Orthogonal Frequency Division Multiplex

I'm working on optical communication systems involving the modulation scheme OFDM (Orthogonal Frequency Division Multiplex). This technique has been widely used for wireline and wirless communications (e.g. DSL, WLAN) and has recently gained much attention in optical communications as it's a promising approach to overcome the difficulties with arriving at data rates of 100 Gbit/s and beyond. Coherent detection and polarization multiplex are two key technologies for reaching this very high transmission speed. The aim of my work is to find appropriate implementation parameters for a single-chip-solution of an optical OFDM transmitter by software simulations. In this way the practical feasibility of this technology shall be demonstrated for the first time. One of my main tasks is the development of a simulation system in C++.
