Response system and method of optical nonlinear function

The invention relates to a response system of an optical nonlinear function, and the system comprises a signal transmitting unit and a light force micro-cavity unit, the signal transmitting unit is used for transmitting a to-be-processed optical signal to the optical force micro-cavity unit; the optical force microcavity unit is used for responding to the optical signal to be processed and generating a first target signal through coupling of an optical field and a mechanical field in the optical force microcavity unit, and the first target signal is a nonlinear response signal of the optical signal to be processed. According to the method and the device, the problems of relatively high power consumption and relatively high time delay in a neural network calculation method based on a light field are solved, and a low-power-consumption and low-time-delay processing mode is realized.
