Abstract

The invention discloses an optical signal processing chip based on an arrayed waveguide grating (AWG). The optical signal processing chip comprises the AWG, a phase and amplitude control array and a reflector array, wherein the AWG projects different frequency components of an incident light signal to different positions in space, then performs amplitude and phase control on each frequency component, then returns each frequency component to the phase and amplitude control array through the total reflector, returns along the original path, finally returns to an input waveguide of the AWG, and is separated from the incident signal through the circulator. According to the technical scheme of the invention, by controlling the phase shift array and the amplitude modulation array, the incident light signal can be processed in the frequency domain, and the functions of an optical filter and a waveform generator are realized.
