We show that it is unreliable to determine the coupling condition of optical resonances by analyzing the extinction ratio change with wavelengths. We propose and demonstrate the unambiguous discrimination between under- and over-coupled resonances using binary phase modulation in power transmission measurement.

在没有先验知识的情况下区分欠耦合共振和过耦合共振

我们表明，通过分析消光比随波长的变化来确定光学谐振的耦合条件是不可靠的。我们提出并证明了在电力传输测量中使用二进制相位调制来明确区分欠耦合谐振和过耦合谐振。
