Abstract :
Two novel optical phase modulation formats, the staggered differential phase-shift keying (SDPSK) with return-to-zero (RZ) and carrier-suppressed return-to-zero (CSRZ) shape, are proposed and compared by numerical simulation for 100 Gbit/s medium-range transmission applications. The demodulation of two phase formats can be achieved on 1 bit rate through only one Mach-Zehnder delay interferometer and a balanced receiver. Superimposed RZ and CSRZ signals are extracted and recovered to compare their transmission performance.
