  • IFOG and IORG Gyros: A Study of Comparative

    2019-11-22 · A new step to achieve the miniaturization of the gyro is to perform the passive ring resonator by means of an integrated optical waveguide made of high-index-contrast materials like silica-on-silicon, silicon-on-insulator, III–V semiconductors (InP), or silicon nitride (Si 3 N 4). Then, this solution gets to what is called the IORG.
