Modal decomposition of light has been known for a long time, applied mostly to pattern
recognition. With the commercialization of liquid-crystal devices, digital holography as an …

Since the discovery that tightly focused femtosecond laser pulses can induce a highly
localised and permanent refractive index modification in a large number of transparent …

Mode-division multiplexing over 33-km few-mode fiber is investigated. It is shown that 6× 6
MIMO processing can be used to almost completely compensate for crosstalk and …

In recent years, space-division multiplexed (SDM) transmission in multimode and multicore
fiber structures has been attracting growing interest as a mean of scaling the capacity of the …

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

Explosive growth in demand for data traffic has prompted exploration of the spatial
dimension of light waves, which provides a degree of freedom to expand data transmission …

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) …

Few-mode fibers (FMFs) have found applications in optical communications and sensors
with attractive features that standard single mode fiber (SSMF) do not possess. We report …

The demonstration of a three‐dimensional tapered mode‐selective coupler in a photonic
chip is reported. This waveguide‐based, ultra‐broadband mode multiplexer was fabricated …
