High-performance photonic analog processing chip is the core component of microwave photonics processing system. In this paper, an ultra-wideband reconfigurable photonic analog computing chip was realized by optimizing the optical waveguide network structure, which can realize arbitrary switching and tuning of various analog signal processing functions by configuring topological networks. The optical matrix computing chip with self-configuration capability and the on-chip photonic convolution accelerator for image processing were also studied. Finally, prospects of cross research between microwave photonics and artificial intelligence were provided.
