中文摘要：

从产量和戒指共鸣器的落下港口基于传播系列的对比比率的测量，一个有效方法被建议提取联合比率和综合光波导戒指共鸣器的双程的损失。离子交换技术在 K9 光玻璃底层准备的一个跑道共鸣器的参数被检验，它表明这个方法的有效性。精确性和这个方法的适用的范围也被讨论。

英文摘要：

Based on the measurement of the contrast ratios of the transmission spectra from the throughput and drop ports of ring resonator, an efficient method is proposed to extract the coupling ratio and round-trip loss of the integrated optical waveguide ring resonator. The parameters of a racetrack resonator prepared by ion-exchange technique in K9 optical glass substrate are examined, which demonstrates the validity of this method. The accuracy and applicable range of this method are also discussed.
