Here we highlight that nonlinear devices that operate as “electromagnetic diodes” for individual port excitations, cannot possibly provide a robust optical isolation under a simultaneous port excitation. Moreover, in the lossless case, typical nonlinear structures, despite being nonreciprocal, are time-reversal invariant, and thereby are inherently bi-directional.
