摘　　要：基于Mie理论研究了球形光学微腔的光学特性,通过计算内场和散射场展开系数随着尺寸分布的变化确定了共振发生的位置,给出了计算球形微腔散射场和内场的计算公式,并数值模拟了结构共振情形下的内场分布情况,分析了微腔内的光振荡特性.Optical characteristics of the spherical microcavity are studied based on the Mie theory, the resonances are located by the variation of internal field coefficients and scattering coefficients with the size parameters. The computing formulas for scattering field and internal field of spherical microcavity are given. The internal field distributions are numerical simulated at the resonant conditions. The optical resonance characteristics are analyzed.
