Abstract
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 (M, M, . . . ) and a portion of each of the N propagating optical signals is sampled at a receiving end of the data transmission network. N−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 (M, M, . . . ) at the receiving end of the data transmission network and N−1 measurements are extracted from the sampled signals. The extracted N−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.
