Abstract

In optical circular cavities, backscattering due to refractive index inhomogeneity and sidewall roughness can cause degenerate resonant modes to split. In this paper, a steady-state field model for circular cavities with backscattering is established and solved. The splitting conditions of the reflection and the transmission spectra and for obvious splitting are discussed. The proposed analytical model and the obtained mode splitting conditions are concise and feasible, which will provide great convenience to the evaluation or anticipation of the backscattering-induced mode splitting. The insights provided by this paper will also serve as a valuable reference for circular resonators of other configurations.
光学圆腔中后向散射对模式分裂的模型及影响
在光学圆腔中,由于折射率不均匀性和侧壁粗糙度引起的后向散射会导致简并共振模式分裂。本文建立并求解了具有后向散射的圆形腔的稳态场模型。讨论了反射光谱和透射光谱的分裂条件以及明显分裂的条件。所建立的解析模型和得到的模分裂条件简洁可行,为后向散射诱导模分裂的评价或预测提供了极大的便利。本文提供的见解也将为其他结构的圆谐振器提供有价值的参考。

期刊介绍: This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
