The application discloses a Mach-Zehnder modulator-based nonlinear calculation method and system, and relates to the technical field of optical fiber communication, wherein the Mach-Zehnder modulator-based nonlinear calculation method comprises the following steps: loading an optical carrier generated by a laser into an input port of a Mach-Zehnder modulator (MZM); loading a direct current bias voltage into upper and lower arms of the MZM, and loading data requiring nonlinear calculation into the upper and lower arms of the MZM as an alternating current voltage after the data are converted into an electrical analog signal; adjusting a voltage difference of the direct current bias voltage loaded into the upper and lower arms, so that the MZM is in a bias point in different states; and obtaining a nonlinear calculation result according to output optical signals of the bias points in different states of the MZM. The application utilizes different forms corresponding to different bias points of the MZM to realize the nonlinear calculation with fast response time and low energy consumption, and reduces the dependence on electrical devices.
