Claim:
1. An optical transmitter, comprising: a drive signal generator configured to generate a first data signal corresponding to a first data stream and a second data signal corresponding to a second data stream distinct from the first data stream; a polarization compensator configured to: a first electro-optic modulator configured to modulate an optical carrier based on the first set of pre-distorted drive signals to generate a first modulated optical signal; a second electro-optic modulator configured to modulate the optical carrier based on the second set of pre-distorted drive signals to generate a second modulated optical signal; a phase shifter configured to cause a shift in the phase of the first modulated optical signal relative to the phase of the second modulated optical signal based on the phase shift signal; and a polarization-division multiplexer configured to polarization multiplex the first modulated optical signal with a first polarization and the second modulated optical signal with a second polarization for transmission over the optical link.
