类轴子粒子（Axion-like particles，ALP）是一种未被发现的赝标量粒子，是超轻暗物质的候选者。ALP与光子轻微相互作用并引起线偏振光的旋转振荡。暗物质轴子搜索与riNg腔实验（DANCE）搜索ALP暗物质放大旋转振荡与蝴蝶结环腔。线性极化的同时谐振对于放大载波场和ALP信号两者以及实现设计灵敏度是必要的。由于蝴蝶结环腔中s偏振和p偏振之间的谐振频率差，当前原型实验DANCE Act-1的灵敏度比预期低约三个数量级。为了调节谐振频率差，提出了引入辅助腔的方法。在考虑光损耗的情况下，设计了一个辅助腔，可以抵消谐振频率差，实现同时谐振。我们还证实了DANCE Act-1在有辅助腔的情况下可以达到原有的灵敏度。
Axion-like particles (ALPs) are undiscovered pseudo-scalar particles that are candidates for ultralight dark matter. ALPs interact with photons slightly and cause the rotational oscillation of linearly polarized light. Dark matter Axion search with riNg Cavity Experiment (DANCE) searches for ALP dark matter by amplifying the rotational oscillation with a bow-tie ring cavity. Simultaneous resonance of linear polarizations is necessary to amplify both the carrier field and the ALP signal, and to achieve the design sensitivity. The sensitivity of the current prototype experiment DANCE Act-1 is less than expectation by around three orders of magnitude due to the resonant frequency difference between s- and p-polarization in the bow-tie ring cavity. In order to tune the resonant frequency difference, the method of introducing an auxiliary cavity was proposed. We designed an auxiliary cavity that can cancel out the resonant frequency difference and realize simultaneous resonance, considering optical loss. We also confirmed that the sensitivity of DANCE Act-1 with the auxiliary cavity can reach the original sensitivity.
