In this paper, we describe recent progress in space-division multiplexed (SDM)
transmission, and our proposal and demonstration of dense space-division multiplexing …

Recent developments in spatially multiplexed optical communication systems demand a
deeper understanding of mode coupling effects in fibers. Spatial multiplexing is being …

The potential transmission capacity of a standard single-mode fiber peaks at around
100Tb/s owing to fiber nonlinearity and the bandwidth limitation of amplifiers. As the last …

In this paper, we review linear propagation effects in a multimode fiber (MMF) and their
impact on performance and complexity in long-haul mode-division multiplexing (MDM) …
