论文摘要
我们在光学微腔的共振光谱中观察到精细的结构。我们确定频谱中极化分辨模式，发现共振频率根据理论预测分裂。观察到的精细结构主要是由光学自旋 - 轨道耦合和非顺式传播和反射引起的。两种效应都是内在的，即存在于理想的旋转对称系统中，并且与曲率的镜像半径成反比。对于曲率半径较小的腔体，精细结构对共振光谱的影响很重要且不可避免，因此应考虑到。
We observe fine structure in the resonance spectra of optical microcavities. We identify the polarization-resolved modes in the spectrum and find that resonance frequencies split in accordance with the theoretical prediction. The observed fine structure is dominantly caused by an optical spin-orbit coupling and non-paraxial propagation and reflection. Both effects are intrinsic, i.e. present in an ideal rotation-symmetric system, and scale inversely proportional to the mirror radius of curvature. For cavities with a small radius of curvature, the influence of fine structure on the resonance spectrum is important and unavoidable and should thus be taken into account.
