    • A method of transmitting N optical signals along a multimode optical fiber where each of the N 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. N 2 - 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 N 2 -1 measurements are extracted from the sampled signals. The extracted N 2 -1 measurements are used to solve a matrix equation ( T ⋅ Λ ) \ V ) = τ\ V ) where A represents generated SU(N) matrices, τ represents the extracted measurements, and |V> represents principal state eigenvectors of an output matrix corresponding to the N optical signals at the receiving end of the data transmission network.
    • 一种沿着多模光纤发送N个光信号的方法,其中N个信号中的每一个包括N个不同的叠加传输模式(M1,M2,...),并且N个传播光信号中的每一个的一部分在接收端被采样 的数据传输网络。 N2-1个不同的测量条件是从数据传输网络接收端的传输矩阵T和对应于叠加的传输模式(M1,M2,...)的特殊的酉矩阵组SU(N)导出的,N2 从采样信号中提取-1个测量值。 提取的N2-1测量用于求解矩阵方程(T⋅Λ)\ V)=τ\ V)其中A表示生成的SU(N)矩阵,τ表示提取的测量值,| V>表示主状态特征向量 对应于数据传输网络的接收端处的N个光信号的输出矩阵。
