Orbital chirality of light in few-mode step-index optical fibers

APL Photonics
A physical system is considered chiral when it can be distinguished from its mirror image, regardless of the applied translation and rotation. An electromagnetic wave can be chiral through its two essential forms of angular momenta: spin and orbital ...

Toward Pbit/s Optical Transmission: A Review of Few-Mode Fiber Demultiplexing Technologies [PDF]

ITM Web of Conferences
Because the global data traffic has grown so rapidly, the transmission capacity of traditional single-mode fibers has already approached the Shannon limit, which is why few-mode fiber (FMF), which exploit the orthogonality of spatial modes for mode ...
