利用苯二甲酸丙二醇酯（PTT）聚合物微米线从生物相容性聚合物材料聚乙烯吡咯烷酮（PVP）水溶液中提拉制备得到直径为10~300 μm的橄榄球形光学微谐振器。将波长为532 nm的绿光和波长为671 nm的红光分别耦合到最大直径为94.7 μm和68.3 μm的橄榄球形微谐振器，观察了其谐振特性。利用1549~1552 nm的连续光源对直径为94.7 μm的橄榄球形微谐振器进行了光学性能测试，测量了其吸收光谱。观察到明显的回音壁模式吸收峰，测得其品质因子为1.05×105。

Rugby-shape optical micro-resonators with diameters of 10~300 μm are fabricated by drawing poly (trimethylene terephthalate) (PTT) microwires immersed in biocompatible polyvinylpyrrolidone (PVP) polymer aqueous solution. Resonating characteristics are observed by coupling 532 nm green light and 671 nm red light respectively into the rugby-shape optical micro-resonators with diameters of 94.7 μm and 68.3 μm. By coupling 1549~1552 nm light into the rugby-shape optical micro-resonator with a diameter of 94.7 μm, absorption spectra are obtained and whispering gallery mode-based absorption peaks are observed, with a measured quality factor of 1.05×105.
