1. An on-chip adaptive optical receiver system, which is applied to optical communication, the on-chip adaptive optical receiver system comprising: an antenna array, an optical phased array, and an optical receiving module, wherein an output end of the antenna array is connected to an input end of the optical phased array, an output end of the optical phased array is connected to an input end of the optical receiving module, and a feedback end of the optical receiving module is connected to a receiving end of the optical phased array;
the antenna array is configured for separating received spatial light to obtain a plurality of sub-light spots and outputting the sub-light spots to the optical phased array;
the optical phased array is configured for performing phase-shifting processing and beam combining processing on the sub-light spots to obtain combined light, and outputting the combined light to the optical receiving module;
the optical receiving module is configured for demultiplexing the combined light to obtain beacon light;
the optical receiving module is further configured for detecting intensity information of the beacon light, generating a feedback signal according to the intensity information, and outputting the feedback signal to the optical phased array; and
the optical phased array is further configured for performing compensation phase-shifting processing and intensity equalization processing on the sub-light spots according to the feedback signal to obtain compensated combined light, and outputting the compensated combined light to the optical receiving module.
