This paper reviews technological options for the modulation formats for serial optical
transmission of 100Gb/s and beyond. In the first part an overview on various modulation …

We designed and fabricated a multi-core fiber (MCF) in which seven identical trench-
assisted pure-silica cores were arranged hexagonally. To design MCF, the relation among …

A novel low-complexity coherent receiver solution is presented to improve spectral efficiency
in wavelength-division multiplexing (WDM) systems. It is based on the receiver-side partial …

We experimentally demonstrate 101.7-Tb/s transmission over 355 km spans of standard
single-mode fiber (SSMF) at a net spectral efficiency of 11 b/s/Hz. A total of 370 dense …

Based on a recently introduced model of non-linear propagation, we propose analytical
formulas for the capacity limit of polarization-multiplexed ultra-dense WDM uncompensated …

We extend the theory of parametric noise amplification to the case of transmission systems
employing multiple optical phase conjugators, demonstrating that the excess noise due to …

We demonstrate that channel spacing can be reduced to values smaller than the Nyquist
channel spacing over transoceanic distance. Modulation memory induced by constrained …

Space domain is regarded as the only known physical dimension left of lightwave to exploit
in optical communications. Recently, lots of research efforts have been devoted to using …

We report on a full C+ L-band erbium-doped fiber amplified (EDFA) submarine transmission
experiment of 178 wavelength-division multiplexed channels of 49-GBd polarization …
