All-optical mode division demultiplexing

摘要: Methods of decoding N superimposed coherent optical transmission modes transmitted along a multimode fiber are provided where the signal detector comprises detection hardware and digital processor. The signals split into channels hardware, which is used to measure phase amplitude output as vector field matrix [ e ] 1 xn . processor determines principal states PS out 1xn from state eigenvectors an corresponding propagating at receiving portion data link extracts input [M] In using , signals, time delay τ each signal. Optical receivers for execution methodology disclosed contemplated herein also provided.
