“…And the corresponding limited sensitivities of RFOG are about 1.66°/h and 0.86°/h, respectively. Compared with the reported work, this gyroscope sensitivity based on the hybrid resonator is higher than that based on the InP resonator, the polymer resonator and the LiNbO 3 resonator32, but is lower than that based on the silica fiber/waveguide resonator and the PBF resonator93037. However, the ROG based on the hybrid resonator still reaches the level of the rate-grade and tactical-grade gyroscope, and shows wide applications.…”

“…For the traditional ROG resonators, the TDWS are from about several to several hundred pm/°C. For example, the TDWS of the silica fiber resonator is about 7.6 pm/°C, and that of the polymer resonator is always more than one hundred pm/°C32. At present, the ROG resonator based on PBF shows the lowest TDWS of about less than 1 pm/°C36.…”

“…Compared with the reported ROG resonators including the silica fiber resonator30, the glass waveguide resonator31, the polymer waveguide resonator32, the InP waveguide resonator33, the LiNbO 3 waveguide resonator34, the hollow-core photonic bandgap fiber (PBF) resonator9 and etc., the hybrid resonator shows a better thermal stability. Generally, the thermal sensitivity of traditional ROG resonators is estimated by 35, where n and dn/dt are the refractive index and the TOC of waveguide material, α sub is the TEC of substrate.…”

“…Therefore, by using the hybrid resonator, the polarization noise and the temperature noise in RFOG can be effectively eliminated. Then, we estimated the limited sensitivity of RFOG based on hybrid resonator only taking account of the shot noise from the photodiodes included in gyroscope readout system by32…”

Polarization error and temperature noise are two main limits to the performance of resonant fiber optic gyroscope (RFOG). To overcome these limits, we demonstrated a hybrid resonator consisting of a polymer-based long-range surface plasmon polariton (LRSPP) waveguide coupler and a silica fiber. Single-polarization property of LRSPP waveguide and the offsetting of the opposite thermo-optical characteristics between the polymer-based LRSPP waveguide and the silica fiber can effectively inhibit both the polarization error and the temperature noise of RFOG. The measured resonance spectrum of the hybrid resonator shows the absence of polarization noise. The temperature dependence of wavelength shift (TDWS) of resonator dropped to about 2 pm/°C, or even to 0 pm/°C with optimal structure, which dramatically improves the temperature stability of gyroscope system. In addition, the hybrid resonator also shows tremendous application potential in rate-grade and tactical-grade gyroscopes.

“…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.
