Abstract
We introduce two important technologies for development of next generation ultra-high-speed optical communications: (i) polarization multiplexing, phase modulation with digital coherent detection, and (ii) OFDM-based optical fiber transmission. In both schemes, digital signal processing plays a key role in recovering the signal and mitigating the detrimental effects from optical signal transmission. We further describe a novel three dimensional low-density parity check (LDPC) coded modulation scheme, including its principle and system performance.
