From: Efficient dispersion modeling in optical multimode fiber
a Spectral correlation of MMF transmission and focusing through MMF using \(h = 3,5,21\) TM measurements. b With h = 5, we computed the focus contrast η at each spatial channel and all wavelengths, and visualized the spatial maps of maximal focus contrast and bandwidth of reconstructed channels for two polarization states. The scale bars are 20 μm
