ing at the quality of the light beam output by the silicon-based optical phased array chip affected by the phase noise during the waveguide etching and bonding process, a phase controller is developed based on the stochastic parallel gradient descent algorithm with a high-speed single-point photodetector as the performance evaluation function collector. Construct a one-dimensional 64-element silicon-based optical phased array chip beam optimization principle experimental system, and realize the fast phase noise compensation of silicon-based optical phased array chip. Then, we study the influence of the matching relationship between the performance of the phase controller and the response characteristics of the silicon-based optical phased array chip on the beam optimization effect, the influence of the initial light field intensity on the convergence time of the stochastic parallel gradient descent algorithm, and the influence of the ambient temperature on the phase noise compensation effect. The experimental results show that the time for the system to complete the single-angle beam optimization is 0.26 s, and the optimized beam indicators are consistent with the device design.
