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

摘要： A method of superimposing N optical transmission modes for collective transmission along a multimode optical fiber is provided where each of the N optical signals comprises N distinct superimposed transmission modes (M1, M2, . . . ) and a portion of each of the N propagating optical signals is sampled at a receiving end of the data transmission network. N2−1 distinct measurement conditions are derived from a transmission matrix T and a special unitary matrix group SU(N) corresponding to the superimposed transmission modes (M1, M2, . . . ) at the receiving end of the data transmission network and N2−1 measurements are extracted from the sampled signals. The extracted N2−1 measurements are used to solve a matrix equation corresponding to the generated SU(N) matrices and the output matrix transposed and used to generating principal state launch conditions from the eigenvectors of the transposed output matrix to form a principal state in each of the N optical signals.
