We present and experimentally demonstrate a scalable, zero-static-power photonic tensor accelerator based on non-volatile silicon material transformation. By performing high-temperature thermal annealing on silicon waveguide phase shifters, we configured the non-volatile weights of photonic computing units.In the experiment, we designed and fabricated a 64-channel FFT-mesh to perform zero-power convolution computation. Nonvolatile configuration of MZIs achieves a weight resolution of up to 10 bits, yielding high-fidelity 64×64 optical computing matrices with a fidelity of 0.972.
