Coherent optical OFDM: theory and design.
TL;DR: The receiver-based digital signal processing to mitigate self-phase-modulation (SPM) and Gordon-Mollenauer phase noise, which is equivalent to the midspan phase conjugation is shown.
Journal ArticleDOI
Coherent optical orthogonal frequency division multiplexing
William Shieh,C.R.N. Athaudage +1 more
TL;DR: In this article, a coherent optical orthogonal frequency division multiplexing (OFDM) was proposed to combat dispersion in optical media, and it was shown that optical-signal-to-noise ratio penalty at 10 Gbit/s is maintained below 2 dB for 3000 km transmission of standard-singlemode fiber without dispersion compensation.

OFDM for Optical Communications
William Shieh,Ivan B. Djordjevic +1 more
TL;DR: In this paper, the authors present a comprehensive overview of optical OFDM signal processing, with a distinctive focus on its broad range of applications, including free-space communications, optical access networks, and metro and log haul transports.
Journal ArticleDOI
107 Gb/s coherent optical OFDM transmission over 1000-km SSMF fiber using orthogonal band multiplexing
William Shieh,Qi Yang,Yiran Ma +2 more
TL;DR: The first experimental demonstration of 107 Gb/s QPSK-encoded CO-OFDM signal transmission over 1000 km standard-single- mode-fiber (SSMF) without optical dispersion compensation and without Raman amplification is presented.
Journal ArticleDOI
1-Tb/s single-channel coherent optical OFDM transmission over 600-km SSMF fiber with subwavelength bandwidth access.
TL;DR: A 1-Tb/s single-channel coherent optical OFDM signal consisting of continuous 4,104 spectrally-overlapped subcarriers is generated using a novel device of recirculating frequency shifter using a single laser with superior flatness and tone-to-noise ratio (TNR).
