Crystalline waveguides for optical gyroscopes
WebMar 4, 2024 · The new type of gyroscope has achieved something considered a benchmark for gyroscopes: the ability to measure the rotation of the earth. "For more than 20 years, researchers have speculated about placing optical gyroscopes onto a chip very much like the highly successful MEMS gyroscopes. But until recently, there have been very few … WebOur chip-based microresonator gyroscope uses silica as a gain medium to generate counter-propagating stimulated Brillouin lasers. These lasers sense the non-reciprocal Sagnac shift under rotation. The device performance is demonstrated by measurement of the Earth's rotation. This gyroscope paves the way towards an all-optical inertial …
