Fig. 4: Robustness of the skin effect at the presence of different degrees of lattice disorder.
From: Dynamic control of 2D non-Hermitian photonic corner skin modes in synthetic dimensions
The randomness is introduced to the intensity modulation of the lattice and the pulse is injected at (x, y) = (0, 0). a, b Experimental observation of robustness of the corner skin mode and skin effect in a lattice with moderate disorder (ηy = ηx = 0.5, 1). Here the disorder leads to a relaxed spatial confinement of light without breaking the localization of light. c, d Breakdown of the localization in the presence of strong disorder (ηy = ηx = 1.5, 2). Light can diffuse arbitrarily far away until they are limited by the size of the experiment. In a–d, from left to right the snapshots are shown for time steps 1, 5, 13, respectively.
