摘要
采用聚苯乙烯材料制作出不同直径(50~250 μm)的球形光学微腔并实现了微腔与锥形光纤的耦合,测量了球形光学微腔在1570~1576 nm波长范围内的吸收光谱,实验结果表明球形光学微腔在这一波长范围内可发生基于回音壁模式(WGM)的光学谐振,且WGM吸收峰的相邻波长间隔随着聚苯乙烯微球直径的增大而减小。通过吸收光谱计算了聚苯乙烯微球在其本征频率下的品质因子,结果表明微球品质因子数量级均在104以上。
Abstract
Spherical optical microcavities with different diameters (50~250 μm) are fabricated using polystyrene (PS), and they are coupled to tapered fibers. Absorption spectra of the spherical optical microcavities in wavelength range of 1570~1576 nm are measured. Experimental results show that whispering gallery mode (WGM)-based optical resonation occurs in the microcavities in this wavelength range. The wavelength interval between the adjacent resonating modes decreases with the increase of the PS sphere diameters. Quality factors of the PS spheres at the eigen frequencies are calculated according to the absorption spectra, and the results show that values of the quality factors are higher than 104.
