Capacity Trends and Limits of Optical Communication Networks Discussed in this paper are: optical communication network traffic evolution trends, required capacity and challenges to reaching it, and basic limits to capacity.
TL;DR: The history of traffic and capacity growth and extrapolations for the future, and fibers supporting multiple spatial modes, including multimode and multicore fibers, and the role of digital processing techniques are recounted.

Geometric requirements for photonic lanterns in space division multiplexing.
TL;DR: This work uses modal analysis, the beam propagation method, and a transfer matrix technique to analyze the lanterns throughput along with its mode dependent loss and shows that unitary coupling between single-mode fibers and a multi-mode fiber is only possible by optimizing the arrangements of the cores.

Mode group division multiplexing in graded-index multimode fibers
Bernd Franz,Henning Bulow +1 more
TL;DR: The potential of mode groups for mode group division multiplexing (MGDM) is studied and single-mode group transmission experiments at 10 Gb/s per mode group, experimental mode group launching by phase mask, and concepts for passive optical mode demultiplexers are discussed.

Dispersive multiplexing in multimode optical fiber
