Photonic Lantern
The photonic lantern is a mode multiplexer/ demultiplexer used to improve the
transmission capacity. The SMF cluster is embedded into a low refractive index capillary
for adiabatic tapering, and then the tapered end is spliced with a few-mode fibre,
fundamental mode in SMF is converted into the specific modes in FMF to realize a
mode conversion and multiplexing ,The photonic lantern utilizes the orthogonality
among various modes arising in few-mode fibres to greatly increase the number of data
transmission channels and improve the transmission capacity.
