Abstract
Mode division multiplexing (MDM) is a promising technology for alleviating network traffic congestion in order to future proof current local area network infrastructure. In view of the capacity limits of multimode fiber in the advent of tremendous data growth, various dimensions for multiplexing and modulating data have been commercially deployed in the intensity, phase, wavelength and time domains. The eigenmode dimension, however, has been relatively untapped. This paper models the MDM of spiral-phased donut modes of different diameters in MMF for increasing the data capacity. A data rate of 40Gbit/s up for a distance of 1500 meters is achieved. Analyses of the power coupling coefficients and modal delays at the photodetectors are analyzed for different mode vortex orders.
