Resonant microphotonic gyroscope
Open accessAbstract
It has been known for four decades that high finesse millimeter-scale optical cavities can produce high-performance, compact optical gyroscopes. Yet, a practical implementation of such a device has been hindered by multiple technical challenges, including Rayleigh scattering and optical nonlinearity of the cavity material. In this Letter we report on the implementation of an integrated passive gyroscope using a monolithic cavity characterized by 7 mm diameter, finesse of 105, and Rayleigh backscattering less than 10 ppm. The device is characterized with quantum noise limited angle random walk of 0.02 deg/h1/2, and bias drift of 3 deg/h, corresponding to detection of rotation-originated optical path change of 1.3×10−16 cm.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
