Paper Abstract

We propose a configuration consisting of several passive ring resonators named as fast-light enhanced ring resonator, coupled to an active ring laser for introducing anomalous dispersion. Theoretical analysis indicates that the introduced anomalous dispersion allows the frequency shift to be improved as large as one order of magnitude due to Sagnac effect when the structure is rotated, namely having the same rotational sensitivity compared to a standard ring-laser gyroscope (RLG) with tenfold size as that of the proposed structure. In this paper, the impact of passive ring resonator number is discussed and deduced, which manifests that only odd number of passive rings will produce effective anomalous dispersion, thus improve the rotational sensitivity. The configuration proposed here will have broad prospect in realizing highly integrated on-chip laser gyroscope for rotation sensing.
