In recent years, quantum entanglement has been widely used in quantum communication, quantum computation and so on. Therefore, it is of great significance to prepare high-performance and integrated quantum multicomponent entanglement sources. The silicon nitride microring resonator is pumped by a tunable laser in this work, and four wave mixing occurs in the resonator under the action of third-order nonlinear effect, resulting in the generation of signal light and idle light. Then based on the entanglement criterion for judging the entanglement between signal and idle light, the degree of entanglement between signal and idle light is calculated. The results show that eight pairs of two-component continuous variable quantum entangled states can be generated in the microring resonator. Besides, the entanglement source system has several advantages such as small size, low power consumption and simplified integration, which has important research value in the field of integrated optical quantum chips.
