We demonstrate mode-multiplexed transmission over the first 9 mode group of 26 km long graded-index multimode fiber achieving a record spectral efficiency of 90 bit/s/Hz.
We discuss the impact of amplification technologies, multi- level constellations, and fiber nonlinearity of the spectral efficiency achievable in fiber-optic networks.
This paper reviews recent progress in high spectral efficiency optical transmission using probabilistic constellation shaping (PCS), and discusses various aspects of PCS from theoretic and practica
We discuss the concept of probabilistic shaping (PS) of constellations, and show that PS allows for flexibly tunable spectral efficiencies at improved transmission performance.
We review current technologies that enable mixed 10 G/40 G transmission in a single DWDM system to achieve capacity upgrade, and discuss promising technologies and challenges for transmitting 100-G
Multiple-antenna wireless - also called MIMO provides order-of-magnitude improvements in throughput and it was originally conceived as a point-to-point scheme where the throughput increases linearl
We review recent progress on high spectral-efficiency optical transmission with per-channel data rates beyond 100 Gb/s.
Perfluorinated graded-index polymer optical fibers (GI-POF) have been developed that offer low losses (50dB/km) and high bandwidth (>0.3GHz km) at data communications wavelengths (0.85 micron an
We present here picosecond time-resolved electro- absorption measurements in GaAs quantum well p-i-n diode structures.
We demonstrate a novel compact AlGaInAs electroabsorption modulated laser at 86 Gb/s including bit-error rate measurements using an optical equalizer.
