Abstract

A review is presented of multilevel coherent and DD optical transmission systems with the aim of a comparative analysis between conventional modulation formats, such as N-PSK, N-QAM and new modulation/demodulation techniques, such as N-4QSK, N-SPSK and PM-DD. Besides the conceptual relevance of new multilevel modulation formats proposed to exploit the transmission characteristics of single-mode optical fibers, important applications can be foreseen like, for example, multiple parallel paths between network nodes or transmission between different processing units of supercomputers.
