1.28 Tbit/s-70 km OTDM transmission using third- and fourth-order simultaneous dispersion compensation with a phase modulator
TL;DR: In this article, a single wavelength channel, optical time division multiplexed and polarisation multiplexing 128 Tbit/s signal has been successfully transmitted over 70 km Third and fourth-order simultaneous dispersion compensation was used with a 10 GHz synchronous phase modulator.
Journal ArticleDOI
10 Gbit/s soliton data transmission over one million kilometres
TL;DR: In this paper, a new technique that incorporates synchronous shaping and retiming using a high speed optical modulator was proposed to overcome the Gordon-Haus limit, the accumulation of amplified spontaneous emission, and the effect of interaction forces between adjacent solitons.
Journal ArticleDOI
Ultrastable harmonically and regeneratively modelocked polarisation-maintaining erbium fibre ring laser
TL;DR: In this paper, a harmonically and regeneratively modelocked erbium fiber ring laser at 1.55 mu m for the first time was reported. But this was achieved with a high speed photodetector and a high Q dielectric filter.
Journal ArticleDOI
Ultrahigh-speed “orthogonal” TDM transmission with an optical Nyquist pulse train
TL;DR: A novel "orthogonal" TDM transmission scheme using an optical Nyquist pulse that enables us to achieve an ultrahigh data rate and spectral efficiency simultaneously without any intersymbol interference (ISI).
Journal ArticleDOI
Parabolic pulse generation by use of a dispersion-decreasing fiber with normal group-velocity dispersion
TL;DR: A new method for generating a parabolic pulse by use of a dispersion-decreasing fiber with normal group-velocity dispersion with highly linear chirp allows for efficient and high-quality pulse compression.
