摘要

We experimentally demonstrate a spectrum-efficient 80-Gbit/s differential phase-shift keying (DPSK) transmitter for a single wavelength channel using phase-interleaving technology without any optical-time or polarization-division multiplexing. Two cascaded independent 40-Gbit/s modulations were time-interleaved to generate an 80-Gbit/s DPSK signal with a compact spectrum. The proposed 80-Gbit/s DPSK transmitter consists of two independent 40-Gbit/s phase modulators only. No additional high-speed pre- or postcoder is required at the transmitter or receiver side. The proposed scheme is potentially cost-effective.
