Photonic Convolution Processing with Large-Scale Spectral Shaper and Frequency Comb

We present a large-scale photonic convolution processor leveraging a frequency comb and integrated multilane spectral shaper supporting 3200 implementable parameters with 72.4 TOPS computation speed. Enhanced scalability by separable convolution approach was also experimentally demonstrated.
