We proposed a 32-channel 50G AWG as the core device to implement the on-chip optical reservoir computing. With appropriate iterative mode and output-level training strategy, the chip has achieved good results in predicting Macky-Glass series. For sequences of 1000 length, this type of optical reservoir calculation can obtain an absolute error of about 0.02 and a relative error of 0.018.
