Significance Gyroscopes,which are the critical components of inertial navigation devices,determine the navigation positioning and attitude control of spacecraft,cranes and vehicle load,and unmanned systems.Due to its high precision,the demand for a miniaturized integrated gyroscope has become urgent.As the market demand for inertial sensor systems grows in the future,micro-nano integrated optical gyroscope technology should be the first choice of the next generation optical gyroscope.Gyroscopes are not only suitable for spacecraft attitude control but can also be used for automatic vehicle navigation systems and safety protection.Integrated optical gyroscopes may fill in the gaps because the global navigation satellite system can be blocked and the weight of laser or optical fiber gyros is extremely large.Resonator micro-nano optical gyroscopes can be used to achieve all-optoelectronic integration,where different separation devices,such as light source,modulator,resonator,and detector,are integrated on the same chip to reduce the volume,weight,and cost of the device.Micro-nano integrated optic gyroscopes should satisfy both the demand for integration and precision.Progress The main problem is that the small area of the closed optical path at the micro/nanoscale decreases gyroscope sensitivity.To achieve a high-precision-resonant integrated optical gyroscope,new principles and technologies must be explored.The research progress of the integrated optical gyroscopes with optical gain,those that are dispersionenhanced,and non-Hermitian optical gyroscopes are reviewed.Because of the limitations of fabrication technology,the propagation loss of passive-optical waveguides cannot meet the requirement of high-precision micro-nano optical gyroscopes.To solve this problem,methods for exciting two laser beams in opposite directions or using the optical gain to compensate for the losses in the resonator are proposed.Several methods for achieving active resonators are introduced,such as semiconductorⅢ-Ⅴmaterials,stimulated
