As a computing accelerator, large-scale photonic spatial Ising machine has great advantages and potential due to its excellent scalability compactness. However, the current fundamental limitation of is configuration flexibility for problem implementation in accelerator model. Arbitrary spin interactions are highly desired solving various non-deterministic polynomial (NP)-hard problems. In this paper, we propose novel quadrature break through by synchronous phase manipulation two sections. The max-cut solution with graph order 100 density from 0.5 1 experimentally demonstrated after almost iterations. Our work suggests flexible machine.
