| 提出了一种基于异质集成波导的微环谐振腔，对其双稳态现象进行了研究分析，并将其应用于全光存储功能的实现。异质集成波导具有超高的克尔非线性效应，不受热光效应和载流子响应的限制，在超快克尔非线性效应的支持下，该结构具有快速全光切换的能力。设计了一个高品质因子Q = 77565的微环谐振腔，用耦合模式理论模拟了其双稳态现象。在峰值功率为474 fJ，宽度为20 ps的脉冲激励下，该微环谐振腔很好地实现了全光存储功能，并通过波分复用的串联微环结构展示了波长可寻址的四位光存储器。研究了基于超高克尔非线性效应的双稳态现象，为实现超快切换速度提供了可能性，在光存储、光开关、人工智能研究等方面具有一定的参考价值。 |

| In this paper, we propose a heterogeneous integrated waveguide platform. The bistable behavior of a micro-ring resonator is observed and analyzed, and the implementation of all-optical memory is shown. The proposed heterogeneous integrated waveguide has strong Kerr nonlinear effect, without the restrictions on thermo-optical effect and free-carrier lifetime. Pure Kerr nonlinear effect enables the ultra-fast all-optical switching. We designed a micro-ring resonator with high quality factor Q = 77565. The bistable behavior was simulated based on coupled mode theory (CMT), and an all-optical memory was realized under the pulse excitation with peak power of 474 fJ and pulse width of 20 ps. Besides, we demonstrated the wavelength addressable four-bit optical memory using four micro-ring resonators cascaded by wavelength division multiplexing. This paper investigates the bistability based on high Kerr nonlinear effect, which provides the possibility of achieving ultra-fast all-optical switching, and shows certain research significance on optical storage, optical switching, and artificial intelligence. |
