Recently, we have proposed a new photonic matrix multiplication circuit using two-layer waveguides as a programmable photonic integrated circuit that combines ease of programming and high fabrication error tolerance. In this study, we experimentally demonstrated the proposed photonic circuit using intensity modulators with the newly developed phase-change material Ge2Sb2Te3S2 (GSTS), and performed 4×4 matrix calculations. Based on the experimental results, we simulated the inference calculations of a convolutional neural network and numerically demonstrated its ability to perform inference with high accuracy.
