  • In order to optimize the performance of an integrated optics gyroscope (IOG), effect on the gyroscope sensitivity resulting from resonant characteristics and structural parameters of a passive ring resonator (PRR), a gyroscope's critical component, was studied based on frequency modulation spectroscopy theory and multi-beams interference method. Because of much more serious light attenuation in waveguides than that in fibers, there were bidirectional function in the design of an IOG while PRR's cavity length and coupling coefficient were changed,being distinguished with the situation in fiber-optic gyroscopes. Finally, a conclusion was drawn that there were optimum parameters determined by the attenuation in waveguides.
