Abstract

Digital switching of the state of polarization (SOP) has been proposed in optical coherent communications for either polarization-independent or SOP-coded transmissions. In both cases external SOP modulators with high insertion losses have been employed. To avoid this penalty, the use of a twin-laser module synchronously operating both in polarization and frequency shift modulation conditions is presented. The feasibility of the relevant schemes for both the aforesaid system types is demonstrated through numerical simulations at 1.55 micrometers wavelength and 155 Mbit/s bit rate.
