利用波动理论和几何光学研究了球面微谐振器尺寸和折射率的微小变化对谐振波长的影响。结果表明，折射率的变化有两方面的影响：一是影响表面的相位跳变，二是影响谐振腔内的光程长度。在某些条件下，外部或内部折射率的影响可以忽略不计。研究了谐振模阶数的影响。最后，将理论分析结果应用于计算温度对共振波长的影响。(c) 2006年美国光学学会。
Wave theory and geometrical optics are used to investigate the effect of small changes in size and index of refraction on the resonance wavelength of spherical microresonators. It is shown that changes in the index of refraction have two effects: These changes affect the phase jump on the surface and the optical path length in the resonator. Under certain conditions the effect of the external or internal index of refraction becomes negligible. The influence of the order number of the resonance modes is investigated. Finally, the results of the theoretical analyses are applied to calculate the effect of temperature on the resonance wavelength. (c) 2006 Optical Society of America.
