“…The quality factor of the WRRs will greatly affect the performance of the MOGs. The prototypes of MOGs have been fabricated in [27][28][29][30]. In this section, we will introduce the WRRs that have been applied to MOGs using different materials, including silicon dioxide (SiO 2 ), indium phosphide (InP), calcium fluoride (CaF 2 ), and polymer.…”

Micro-optical gyroscopes (MOGs) are a type of high-accuracy gyroscope, which have the advantages of miniaturization, low cost, and satisfactory operating power. The quality factor (Q) of the waveguide ring resonators (WRRs) is very important to the performance of MOGs. This paper reviews various MOGs using WRRs made from different materials, including silica, indium phosphide, calcium fluoride, and polymer WRRs. The different architectures of the MOGs are reviewed, such as double-ring resonator MOGs and multiple-ring resonator MOGs. Candidate high-Q WRRs for MOGs, including silicon nitride, lithium niobite, calcium fluoride, and magnesium fluoride WRRs, are also reviewed. The manufacturing process, Q, and integration density values are compared. Summarizing the advanced WRRs and calculating the shot-noise-limited sensitivity are helpful processes in selecting suitable materials to fabricate MOGs.

“…Optical gyros based on the Sagnac effect are attractive sensors for inertial navigation systems [1,2,3,4]. However, both the Fiber Optic Gyroscope (FOG) and Ring Laser Gyroscope (RLG) have some serious disadvantages, as they are bulky, expensive, and energy intensive [5,6,7,8].…”

The Resonant Integrated Optic Gyroscope (RIOG) is a type of high accuracy gyroscope based on the Sagnac effect. A symmetrical resonance curve is very important to the performance of the RIOG. To further investigate and design a RIOG with a waveguide ring resonator, an in-depth research of the asymmetric resonance curve and its influence on the RIOG is fully developed. Four possible optical noises inducing the resonance curve asymmetry are analyzed and their mathematic models are established. These four optical noises are the normal mode effect, the backscattering noise, the backreflection noise and the polarization noise. Any asymmetry of the resonance curve will not only induce a large output bias error into the gyro output, but also seriously decrease the frequency discrimination parameter of the demodulation curve. By using a tunable fiber laser, the high aspect ratio silicon nitride WRR and the silicon dioxide WRR were tested. The experiment measured resonance curves can be well fitted with the theoretical simulation results. The experimental results show that a high aspect ratio silicon nitride waveguide can effectively suppress the polarization noise in the RIOG.

“…For these reasons, there has been intense interest in chipbased Sagnac gyroscopes. Compact or chip-based ring laser gyroscopes [4,5], passive resonant gyroscopes [6][7][8][9], and interferometric gyroscopes [10] have recently been reported.…”
