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

We demonstrate a 3x1 fiber-based photonic lantern spatial-multiplexer with mode-selectivity
greater than 6 dB and transmission loss of less than 0.3 dB. The total insertion loss of the …

We present a new technique allowing the fabrication of large modal count photonic lanterns
for space-division multiplexing applications. We demonstrate mode-selective photonic …

Spatial multiplexer (SMUX) for mode division multiplexing (MDM) has evolved from mode-
selective excitation, multiple-spot and photonic-lantern based solutions in order to minimize …

The majority of optical fiber technology developments in the applied sciences have arisen
from developments in telecommunications. However, the photonic lantern is one of several …

We report transmission experiments in few-mode fibers supporting 6 spatial-and polarization
modes, where low-loss photonic lanterns are used as mode multiplexers. We measured a …

Laser-inscribed 3-D waveguide (3DW) technology has been applied to realize photonic-
lantern spatial multiplexer (SMUX), which potentially enables lossless mode (de) …

We investigate the use of “photonic lanterns” as adiabatic mode converters for space-
division multiplexing (SDM) systems to interface multiple single-mode fibers to a multi-mode …

The emergence of space division multiplexing (SDM) for ultrahigh capacity networks has
heralded pioneering Petabit-class optical transmission systems. In parallel to novel SDM …

To unlock the cost benefits of space division multiplexing transmission systems, higher
spatial multiplicity is required. Here, we investigate a potential route to increasing the …
