From: Multiplexed orbital angular momentum beams demultiplexing using hybrid optical-electronic convolutional neural network

Fig. 2

a-b, c-d, and e-f are the demultiplexing accuracy results of the electronic convolutional neural network (ECNN) and the optical-electronic convolutional neural network (OECNN) with the 5-class, 8-class, and 16-class OAM-coded signals, respectively. Red, purple, green, and blue curves represent the turbulence-free, weak, medium, and strong atmospheric turbulence conditions, respectively. The shaded area represents the range of min-max results from 5 different runs.
