TL;DR: In this article, the authors demonstrate ultradense SDM transmission of 739 WDM 12-Gbd dual polarization signals over 11.3km 6-mode 19-core fiber using the C+L band, achieving a record fiber capacity of 10.16 peta-b/s with an aggregate spectral efficiency of 1099.9 b/s/Hz.
Journal ArticleDOI
Optical frequency domain ranging by a frequency-shifted feedback laser
TL;DR: In this article, the authors describe the theoretical and experimental study of a new technique for optical frequency domain ranging (OFDR) by a frequency-shifted feedback (FSF) laser.
Journal ArticleDOI
1024 QAM (60 Gbit/s) single-carrier coherent optical transmission over 150 km.
TL;DR: A frequency-domain equalization technique and a back-propagation method are adopted to compensate for distortions caused by hardware imperfections and fiber impairments, and 60 Gbit/s polarization-multiplexed transmission over 150-km has been achieved at 3 Gsymbol/s within an optical bandwidth of only 4.05 GHz.

TL;DR: A very uniform dispersion of SWNT in PMMA and PS polymers has been realized by using chlorobenzene or tetrahydrofuran as a dispersion solvent, which was difficult to achieve with previous thin-film materials.
Journal ArticleDOI
2048 QAM (66 Gbit/s) single-carrier coherent optical transmission over 150 km with a potential SE of 15.3 bit/s/Hz
TL;DR: This work has successfully achieved a 2048 QAM transmission with a potential spectral efficiency of 15.3 bit/s/Hz in a single carrier coherent transmission over 150 km.
