中文摘要：

波导戒指共鸣器的一种类型，基于 Er3+/Yb3+ 共同做的磷酸盐玻璃和是的使用的热光的效果调节举止，被带上。戒指共鸣器与 400m 的半径由二直波导和戒指波导组成。电极在波导的顶上被蒸发完成热调节。第一，戒指共鸣器的过滤计划被分析，然后，电极的参数怎么影响过滤特征，被讨论。

英文摘要：

A type of waveguide ring resonator, based on Er^3＋/Yb^3＋ co-doped phosphate glass and using thermal-optical effect as tuning manner, is brought up. The ring resonator is composed of two straight waveguides and a ring waveguide with radius of 400 μm. Electrode is evaporated on the top of the waveguide to achieve thermal tuning. Firstly, the filtering scheme of the ring resonator is analyzed, then how parameters of the electrode influence the filtering characteristics is discussed.
