Abstract: An on-chip adaptive optical receiver system, an optical chip, and a communication device are disclosed, which are applied to optical communication. The on-chip adaptive optical receiver system includes an antenna array configured for separating received spatial light to obtain a plurality of sub-light spots; an optical phased array configured for performing phase-shifting processing and beam combining processing on the sub-light spots to obtain combined light; and an optical receiving module 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 and generating a feedback signal according to the intensity information. 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.
