Abstract
We experimentally demonstrate a cost-effective 80-Gbit/s DPSK transmitter using phase interleaving without optical-time/polarization-division multiplexing. Two cascaded independent 40-Gbit/s modulations are time-interleaved to generate 80-Gbit/s DPSK with high spectrum efficiency: 20-dB bandwidth of only 0.68 nm.
