Photon chip phase shifter working point control method and device

The invention discloses a photon chip phase shifter working point control method and device, and the method comprises the steps: obtaining the real-time temperature data of a photon chip, and judging whether the real-time temperature data meets a variable temperature condition or not, if yes, the initial working power of the target phase shifter is obtained from a power-temperature comparison table of the target phase shifter based on the real-time temperature data, and the initial working power is controlled to serve as the working power of the target phase shifter; the working power of the target phase shifter is circularly adjusted through a locking algorithm, so that the target phase shifter works in the optimal working range at the current temperature; wherein the target phase shifter is any one phase shifter in the photon chip. The method can effectively solve the problems that an existing phase shifter working point adjusting method is large in packaging size, large in power consumption, low in respons
