ABSTRACT:
Embodiments of the present invention provide a method and apparatus for producing a phase coded non-return-to-zero (PC-NRZ) optical signal. The method includes providing an input optical signal; providing first and second drive signals, the first drive signal having a first data pattern of first and second signal levels, the second drive signal having a second data pattern, the second data pattern having third and fourth signal levels that toggle at least when the first drive signal changes from the first signal level to the second signal level; and modulating amplitude of the input optical signal with the first drive signal and modulating phase of the input optical signal with the second drive signal to produce the PC-NRZ optical signal. A PC-NRZ optical transmitter and an optical transmission system applying the PC-NRZ optical transmitter are also provided.
