F3: Transceiver circuits for optical communications

Optical communications have been transitioning to a new era where CMOS system integration and electronic signal processing is playing the key role. Targeted areas: equalization and electronic dispersion compensation (EDC); advanced coding and detection techniques, such as FEC, MLSE; Spectral efficient optical modulation with coherent detection modulation formats, for an example, QPSK, DP QPSK, and so on. While 40 Gb/s DP QPSK ASICs are already in the most advanced optical systems, developments with 100 Gb/s requirements are underway.
