Data points for all figures of the research paper "On the advantages of principal modes for multimode SDM tranmission systems".1) File Fig2a.csv - The multimode fiber channel matrix H(w) at the center frequency. This file correponds to a 2-D matrix showing the absolute value of the coupling coefficient.2) File Fig2b.csv - Residual channel when using the principal modes for transmission. This file correponds to a 2-D matrix showing the absolute value of the coupling coefficient.3) File Fig3a.csv - Group delay per principal mode in the selected group;4) File Fig3b.csv - Crosstalk per principal mode in the selected group. Each column contains the crosstalk observed when transmitting a given number of principal modes.5) File Fig3c.csv - Multiple-input single-output array size required to detect each principal mode in the selected group. Each column corresponds to the array size for a different number of transmitted principal modes.6) File Fig4a.csv - Crosstalk per principal mode when 330 tributaries are transmitted. Each column corresponds to the crosstalk of a given principal mode in Fig. 4(a).7) File Fig4b.csv - Multiple-input single-output array size required to detect each tributary (when 330 principal modes are used for transmission). Each column corresponds to the required array size to guarantee the target SNR of 20 dB.File format: '.csv (comma-separated values)'.
