We propose a novel OTDM scheme with hybrid RZ-ASK/RZ-DPSK formats and investigate its demultiplexing performance. Experiment showed the tolerances to demultiplexing timing misalignment were improved by 180% and 70%, for RZ-ASK and RZ-DPSK channels, respectively.
We propose a novel hybrid optical time-division multiplexing (OTDM) approach, which contains hybrid modulation formats of return-to-zero on-off keying and return-to-zero differential-phase-shift keying, and investigate its demultiplexing performance. Compared with conventional OTDM with homogenous modulation format, the target demultiplexed channel in a hybrid OTDM signal suffers from much less degradation...
