Abstract-Recent results obtained on integrated optical gyroscopes are presented in this paper. The sensors configuration, based on high-Q resonators both in silica-onsilicon and InP technologies, is discussed and the estimation of the resonators performance through an accurate optical characterization is reported. On the basis of the numerical and experimental achievements, we demonstrate that resonant micro optical gyros can potentially exhibit resolution values in the range 1-10 °/h, which is demanded by several emerging space applications.

“…They also have efficient coupling with optical fibers, reduced sensitivity to perturbations, and have been used as planar ultra-high-Q resonators [1]. This technology has advantages for many applications, including sensors [2], gyroscopes [3], adjustable delay lines for buffers or true time delay phased array radars [4], and low phase noise oscillators [5]. Ultra-low-loss waveguides require high temperature processing of over 1000 °C and have not been integrated with lasers and photodetectors, which are required for fully integrating the abovementioned photonic systems.…”

Abstract:We demonstrate a novel integrated silicon and ultra-low-loss Si 3 N 4 waveguide platform. Coupling between layers is achieved with (0.4 ± 0.2) dB of loss per transition and a 20 nm 3-dB bandwidth for one tapered coupler design and with (0.8 ± 0.2) dB of loss per transition and a 100 nm 3-dB bandwidth for another. The minimum propagation loss measured in the ultra-low-loss waveguides is 1.2 dB/m in the 1590 nm wavelength regime.

“…The performance of a MOG is determined by the resonance frequency difference in the clockwise (CW) and counterclockwise (CCW) (Haavisto and Pajer 1980;Connors and Mahapatra 1987;Walker and Wilkinson 1983;Naumaan and Boyd 1986;Bismuth et al 1991;Ciminelli et al 2010;Yu et al 2009;Guo et al 2010). Early research is focused mostly in the polymer ring resonator and glass ion exchange waveguide ring resonator.…”

A kind of direct-coupled large-diameter silica on silicon waveguide ring resonator used in microoptic gyro with 4 cm diameter was presented. An optical and electromechanical test platform was designed to investigate the performance of the ring resonator. The resonance curve, demodulation curve and three relative important resonator parameters were obtained. The free spectral range of the resonator, the full width at half maximum of the resonance curve and the finesse of the resonator, are 3 GHz, 73 MHz and 41, respectively. Open-loop experiments of resonator are set up using the acousto-optic frequency modulation spectroscopy technique. The output of MOG is investigated by the platform rotate and equivalent gyro rotate. The slope of the linear fit is about 3.154 mV/( /s) based on the À50$50 /s rotating rates and 0.330 mV/( /s) based on the À900$900 KHz equivalent frequency shift, respectively. The demodulation curve shows a strongly nonlinear and the linear approximation has a great limitation.
