| Outline of Final Research Achievements |
WDM transmission of M-ary modulated signals interleaved with reference light (henceforth referred to as interleaved signals) is numerically studied to verify feasibility of over 1-Tbit/s ultra-high speed optical access systems with the interleaved signals. Availability of an optical phase-locked multi-carrier source on WDM transmission systems are theoretically considered. The electric field enhancement of reference light is proposed and improves dispersion tolerance of the interleaved 16QAM signals by twice as much as the conventional signals.
