The optical component applied to the ultra-small closed-loop fiber optic gyroscope (FOG) is a special optical module composed of fiber ring and optical devices (Y waveguide, coupler, detector, light source) which are fused and assembled according to the sequence of the gyroscope optical path. It can replace the optic fiber, waveguide and other loose parts for direct modular installation on the gyroscope, thus simplifying the gyroscope assembly process. Devices with 1310nm working wavelength are adopted for this module, and the zero bias stability at room temperature is 0.15~0.3°/h. It has the advantages of integration, small size, and is easy to install.
