a Extinction ratio of the MRM as a function of the linewidth of the input partially coherent optical source. The star marks the extinction ratio with a narrow-linewidth laser input, while the dashed line represents the estimated value. b Measured eye diagram of the MRM for partially coherent optical sources with different linewidths at an operating frequency of 140 MHz. c The results on the 4-classification of handwritten digits with the partially coherent optical neural network
