氧化物孔微柱腔中的光学模式
Optical modes in oxide-apertured micropillar cavities
摘要:
我们提出了一个详细的实验表征的光谱和空间结构的限制光学模式的氧化物孔微柱腔,显示出良好的质量厄米高斯分布,很容易模式匹配到外部字段。我们进一步推导出了横模的频率分裂与所期望的Purcell因子之间的关系。最后,我们描述了一种技术来检索的限制折射率分布的模式的空间分布。
英文摘要:
We present a detailed experimental characterization of the spectral and spatial structure of the confined optical modes for oxide-apertured micropillar cavities, showing good-quality Hermite-Gaussian profiles, easily mode-matched to external fields. We further derive a relation between the frequency splitting of the transverse modes and the expected Purcell factor. Finally, we describe a technique to retrieve the profile of the confining refractive index distribution from the spatial profiles of the modes.
