With the feedback technique, the spatiotemporal chaos is controlled in the photorefractive ring oscillator. Numerical simulation results show that the fixed value feedback and variable feedback technologies both can realize the control of spatiotemporal chaos. When the photorefractive ring oscillator system parameters are confirmed, the control of spatiotemporal chaos is realized based on the fixed value feedback. In addtion, the system has the minimum feedback coefficient and the maximum feedback light intensity to realize spatiotemporal chaos control. So the reasonable feedback coefficient and feedback light intensity must be chosen in order to control the spatiotemporal chaos. The feedback technology can not only be used to realize the one-dimensional spatiotemporal chaos control, but also the two-dimensional control, and simultaneously the two control results are similar.
