“…Miniaturized gyroscopes based on semiconductor ring lasers [3][4][5][6] are very interesting devices with a footprint < 100 mm 2 and a theoretical resolution comparable to that one of RLGs but, until now, their experimental demonstration has been prevented by the lock-in effect and the mode competition between the counter-propagating resonant modes.…”

An InP ring resonator with an experimentally demonstrated quality factor (Q) of the order of 10(6) is reported for the first time. This Q value, typical for low loss technologies such as silica-on-silicon, is a record for the InP technology and improves the state-of-the-art of about one order of magnitude. The cavity has been designed aiming at the Q-factor maximization while keeping the resonance depth of about 8 dB. The device was fabricated using metal-organic vapour-phase-epitaxy, photolithography and reactive ion etching. It has been optically characterized and all its performance parameters have been estimated. InP waveguide loss low as 0.45 dB/cm has been measured, leading to a potential shot noise limited resolution of 10 °/h for a new angular velocity sensor.

Low-cost chip-scale optoelectronic gyroscopes having a resolution ≤ 10 • /h and a good reliability also in harsh environments could have a strong impact on the medium/high performance gyro market, which is currently dominated by well-established bulk optical angular velocity sensors. The R&D activity aiming at the demonstration of those miniaturized sensors is crucial for aerospace/defense industry, and thus it is attracting an increasing research effort and notably funds.In this paper the recent technological advances on the compact optoelectronic gyroscopes with low weight and high energy saving are reviewed. Attention is paid to both the so-called gyroscope-on-a-chip, which is a novel sensor, at the infantile stage, whose optical components are monolithically integrated on a single indium phosphide chip, and to a new ultra-high Q ring resonator for gyro applications with a configuration including a 1D photonic crystal in the resonant path. The emerging field of the gyros based on passive ring cavities, which have already shown performance comparable with that of optical fiber gyros, is also discussed.

“…The microoptic gyro (MOG)-based on the planar optical waveguide are further miniaturization and integration of the RLG and FOG. Several attempts have been made by researchers and companies for several years (Lawrence 1983(Lawrence , 1990Geiger et al 1999;Matthews et al 2000;Ayazi and Najafi 2001;Armenise et al 2001;Osiń ski et al 2006). The major advantages of MOG are inherent hardness, being small in size, having low power consumption, and low fabrication cost.…”

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.
