Special Issue Information

Dear Colleagues,

For several decades, gyroscopes have been key sensors for attitude control and autonomous guidance of a wide range of vehicles, such as military and civil airplanes, military ships, submarines, satellites, space launchers, long-range ballistic missiles, and so on. More recently, other gyro application areas have emerged, i.e., robotics, medical instruments, automotive, and consumer electronics.

Photonic gyroscopes, all based on the Sagnac effect, are already on the market with a very good performance (resolution down to 0.01 °/h or better), but they are now facing several challenges, e.g., miniaturization and cost/power consumption reduction, enabling new intriguing applications.

The Special Issue will provide a forum for the latest research activities in the field of integrated microphotonic and fiber-optic gyroscopes and their applications. Both review articles and original research papers are solicited in, though not limited to, the following areas:

  • Micophotonic gyros based on ring lasers;
  • Micophotonic gyros based on passive high-Q resonators;
  • Ultra-high-Q optical cavities intended for gyro applications;
  • Interferometric micophotonic gyros;
  • Emerging concepts of micophotonic gyros;
  • Resonant fiber-optic gyros;
  • Interferometric fiber-optic gyros;
  • Fiber-optic gyros based on optically pumped ring lasers;
  • Readout techniques for resonant and interferometric gyros;
  • Novel applications of integrated microphotonic and fiber-optic gyroscopes.

A room-temperature strip-guided “manufacturable” Silicon-on-Insulator (SOI)/GeSn integrated-photonics quantum-gyroscope chip operating at 1550 nm is proposed and analysed. We demonstrate how the entangled photons generated in Si Spontaneous Four Wave Mixing (SFWM) can be used to improve the resolution of a Sagnac interferometric gyroscope. We propose different integrated architectures based on degenerate and non-degenerate SFWM. The chip comprises several beam splitters, two SFWM entangled photon sources, a pump filter, integrated Mach–Zehnder interferometric gyro, and an array of waveguide coupled GeSn/Ge/Si single-photon avalanche detectors. The laser pumped SWFM sources generate the signal-idler pairs, which, in turn, are used to measure the two-photon, four-photon, and higher order coincidences, resulting in an increasing of the gyro resolution by a factor of two and four, with respect to the classical approach.

In a high accuracy strapdown inertial navigation system (SINS), the ring laser gyroscope’s (RLG) bias changes and the performance decreases due to factors in the RLG’s self-heating and changes in ambient temperature. Therefore, it is important to study the bias temperature drift characteristics of RLGs in high, low, and variable temperature environments. In this paper, a composite temperature calibration scheme is proposed. The composite temperature model introduces the derivative term and the temperature derivative cross-multiplier on the basis of the static model and sets the overlap regions for the piecewise least squares fitting. The results show that the composite temperature model can compensate the bias trend term well at ambient temperature, improve the fitting accuracy, and smooth the output curve. The compensation method has a small amount of calculations and flexible parameter design. The precision of the laser gyros in one SINS is improved by about 64.9%, 15.7%, and 3.6%, respectively, which has certain engineering application value. Full article
