Abstract By combining a silicon-based lithium niobate modulator and a silicon-based Si3N4 resonator with silicon-based photonics technology, a highly systematic design of a hybrid integrated optical gyroscope with enhanced reciprocity sensitivity and a dual micro-ring structure is proposed for the first time in this paper. The relationship between the device's structural parameters and optical performance is also analyzed by constructing a complete simulation link, which provides a theoretical design reference to improve the system's sensitivity. When the wavelength is 1550 nm, the conversion frequency of the dual-ring optical path is 50 MHz, the coupling coefficient is 0.2, and the radius R is 1000 μm, the quality factor of the silicon-based Si3N4 resonator is 2.58×105, which is 1.58 times that of the silicon-on-insulator resonator. Moreover, the effective number of times the light travels around the ring before leaving the micro-ring is 5.93, which is 1.62 times that of the silicon-on-insulator resonator. The work fits the gyro dynamic output diagram, and solves the problem of low sensitivity at low speed by setting the phase offset. This results provide a basis for the further optimization of design and chip processing of the integrated optical gyroscope.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
