Four-mode multiplexing and manipulation technologies are reviewed in the context of space-
division multiplexing (SDM) optical communication systems. These are multiplane light …

We review the current status of mode-division multiplexing (MDM) techniques in fibers and
on chips. Three system applications are introduced, including quasi-single mode …

Photonic technologies offer numerous functionalities that can be used to realize
astrophotonic instruments. The most spectacular example to date is the ESO Gravity …

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 …

The photonic lantern (PL) is a tapered waveguide that can efficiently couple light into
multiple single-mode optical fibers. Such devices are currently being considered for a …

Optical fiber communications rely on multiplexing techniques that encode information onto
various degrees of freedom of light to increase the transmission capacity of a fiber. However …

Trapped in the stringent adiabatic transmission condition of high-order modes, low-loss
fused biconical taper mode selective coupler (FBT-MSC) has long been challenging to …
