摘　　要：Optical bistability can be used to explore key components of all-optical information processing systems,such as optical switches and optical random memories.The hybrid integration of emerged two-dimensional layered PtSe_(2)with waveguides is promising for the applications.We demonstrated the optical bistability in the PtSe_(2)-on-silicon nitride microring resonator induced by a thermo-optic effect.The fabricated device has a resonance-increasing rate of 6.8 pm/mW with increasing optical power.We also established a theoretical model to explain the observation and analyze the device's performance.The study is expected to provide a new scheme for realizing all-optical logic devices in next-generation information processing systems.
