摘要 首次提出了一种由Er3+掺杂有源环谐振器(EDARR)慢光结构构成的光学陀螺仪。详细分析了提高角速度检测灵敏度的原理。推导并讨论了反向传播波间EDARR旋转相位差的表达式。在谐振频率处，当腔内的光功率远大于输入光功率时，相移差具有最大值。我们设计了掺Er3+有源环谐振器慢光系统的实验方案。在光路中引入两个附加偏置相位 ψb = ±π/2，通过记录谐振频率处的光强差和 I0，可以获得输入角速度。基于EDARR的慢光结构可以将角速度检测的灵敏度提高三个数量级。
Abstract An optical gyroscope, which is constituted by Er3+-doped active ring resonator (EDARR) slow light structure, is presented for the first time. The principle of improving the sensitivity of the detection of angular velocity is analysed in detail. The expression of the rotation phase difference of EDARR between the counter-propagating waves is derived and discussed. At the resonant frequency, the phase shift difference has the maximum value when the light power in the cavity is far greater than the input light power. We designed an experimental scheme of Er3+-doped active ring resonator slow light system. Two additional bias phases ϕb = ±π/2 were introduced in the optical path, by recording the light intensity difference and I0 at the resonant frequency , the input angular velocity can be obtained. The slow light structure based on EDARR can enhance the sensitivity of the detection of the angular velocity by three orders of magnitude.
