Active Slow-Light Rotation Sensor

摘要

We study the lasing eigen-modes and dynamics of circular coupled laser array in a rotating framework for ultra-sensitive integrated optical rotation sensing applications. The dependence of the mode and frequency splitting on the array parameters is studied in details. The impact of variations of the resonance wavelength of the individual cavities and the inter-cavity coupling is studied and found to generate a "dead-zone" which limits the sensitivity of the sensor.
