通过测量光学环形腔两个反向传播方向之间的谐振频率差来探索电动力学中的洛伦兹破坏。我们的腔体包含介电元件，这使得我们的腔体对违规行为敏感。激光频率稳定在腔体的逆时针谐振处，透射光反射回腔体，与顺时针谐振点进行谐振频率比较。这种双通道配置可实现零实验，并提供对环境干扰的高共模抑制。我们没有发现 δc/c ≲ 10(-14) 水平上奇宇称各向异性的证据。在标准模型扩展的框架内，与之前的最佳限制相比，我们的结果对三个奇奇偶校验参数 κ(o+)(JK) 的限制提高了 5 倍以上，对标量参数 κ(tr) 的限制提高了 12 倍。
A search for Lorentz violation in electrodynamics was performed by measuring the resonant frequency difference between two counterpropagating directions of an optical ring cavity. Our cavity contains a dielectric element, which makes our cavity sensitive to the violation. The laser frequency is stabilized to the counterclockwise resonance of the cavity, and the transmitted light is reflected back into the cavity for resonant frequency comparison with the clockwise resonance. This double-pass configuration enables a null experiment and gives high common mode rejection of environmental disturbances. We found no evidence for odd-parity anisotropy at the level of δc/c ≲ 10(-14). Within the framework of the standard model extension, our result put more than 5 times better limits on three odd-parity parameters κ(o+)(JK) and a 12 times better limit on the scalar parameter κ(tr) compared with the previous best limits.
