We propose and design a kind of heterogeneous rod-assisted and trench-assisted multi-
core fiber (Hetero-RA-TA-MCF) with 32 cores arranged in square-lattice structure (SLS), and …

We develop an analytical theory which allows us to identify the information spectral density
limits of multimode optical fiber transmission systems. Our approach takes into account the …

We study the achievable rates of submarine fiber systems in the high-dimensional design
space of variables including span length, launch power, number of spatial channels, and …

We report on the first real-time operation of coherent point-to-multipoint in high-speed fiber-
optic communications. The broadcast and aggregation network consists of a 400 Gb/s hub …

In the context of the fifth generation of mobile technology (5G), multiple technologies will
converge into a unified end-to-end system. For this purpose, software defined networking …

Some of the most widespread analytical models for nonlinear propagation in fiber optic
coherent systems are reviewed, highlighting the tradeoffs between accuracy and complexity …

Motivated by results in optical communications, where the performance can degrade
dramatically if the transmit power is sufficiently increased, the channel capacity is …

Mode‐division multiplexing (MDM) using few‐mode fibre (FMF) has received increasing
attention to address the exponential growth of data traffic in long‐haul optical …

Orbital angular momentum (OAM) is a degree of freedom independent of polarization and
frequency of vortex beams. Therefore, the measurement of OAM has attracted great interest …

In order to characterize the channel capacity of a wavelength channel in a wavelength-
division multiplexed (WDM) system, statistical models are needed for the transmitted signals …
