Figure 3: Numerical simulation of propagation of the ODoF.
From: Is there an optimal basis to maximise optical information transfer?
Logarithmic plot of the density in propagation plane (a) and in the output transversal plane (b). Plot of normalised eigenvalue spectra of the OEi of the system (c). Note that the degenerate eigenvalues originate from the time reversal invariance (see Supplementary Section 4 for a discussion).
