Radial Bragg laser as a miniaturized rotation sensor

We present and study theoretically a novel approach for rotation sensing by utilizing radial Bragg lasers (RBL) as a miniaturized optical Gyro. We study the dynamics and steady state of the electric fields evolving in the RBLs under rotation. We show that by utilizing the properties of the steady-state field profile of the RBL rather than a direct measurement of the Sagnac frequency-shift, it is possible to increase significantly the sensitivity for slow rotation rates.
