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 …

A crowd of proteins seems to have gathered around the plus-ends of microtubules. A rapidly
expanding group of proteins known as plus-end tracking proteins (+ TIPs) have been …

We report the successful transmission of ten 494.85 Gbit/s DWDM signals on the standard
50 GHz ITU-T grid over 32× 100 km of ultra-large-area (ULA) fiber. A net spectral efficiency …

This paper reviews recent advances in the generation, detection and transmission of
orthogonal-frequency-division-multiplexing (OFDM) based superchannels, enabled by …

In-phase and quadrature skew inside a coherent receiver, caused by misalignments, can
severely limit performance. Future 400G systems employing higher order modulation …

A 448 Gbit/s single-carrier dual-polarization 16-ary quadrature-amplitude-modulation (DP
16-QAM) signal and a 1.206 Tbit/s three-carrier DP 16-QAM signal are demonstrated using …

The recently reported high spectral efficiency (SE) and high-baud-rate signal transmission
are all based on digital coherent optical communications and digital signal processing …

We experimentally investigate Kerr nonlinearity mitigation of a 28-GBd polarization-
multiplexed 16-QAM signal in a five-channel 50-GHz spaced wavelength-division …

We demonstrate high speed optical transmission systems using digital coherent detection at
all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we …

Since it is difficult to emit a controla IQ modulator emitting modulated lightwave according to
QAM format without sig nal degradation of said emitted signal due to low frequency dither …
