硅光调制器光电延迟反馈系统动力学行为研究

t present, the research of optoelectronic delay feedback system generally adopts bulky optical devices as the nonlinear element of the system. The system has large volume, and is sensitive to the vibration and temperature change in the environment. This is mainly because the scale of the bulky optical element is much larger than the wavelength of light, which is generally greater than 10000:1. While for the silicon optical modulator, such scale is only about 1000: 1. Optoelectronic delay feedback system based on it is more robust and has smaller volume. Therefore, a nonlinear optoelectronic delay feedback system based on the silicon optical modulator is demonstrated. The nonlinear dynamics of the system is studied. Periodic and chimera states, as well as chaos are observed in the experiment. The numerical simulation of the experimental system is carried out and the simulation results are in agreement with the experimental results. The nonlinear behavior of the system can help to further study the nonlinear characteristics of the optoelectronic delay feedback system. The advantages of high bandwidth, low cost and easy integration of silicon optical modulator make it have a wide application prospect.
