ABSTRACT:
A modulation method for optical communication comprises the step of generating an optical signal modulated between a plurality of different states of polarization and between different phase states. The plurality of states of polarization comprises first states of polarization. The first states of polarization define a single great circle on the Poincaré sphere. The method is characterized in that the plurality of states of polarization further comprise one or more second states of polarization located outside the great circle. Such additional second states of polarization increase the symbol alphabet.
