周期性侧面耦合微腔和光子晶体结构的耦合模理论

Coupled-mode theory for periodic side-coupled microcavity and photonic crystal structures

Philip Chak, Suresh Pereira, J. E. Sipe

摘要:

我们使用唯象的哈密顿方法推导出一组耦合模方程,描述光在波导中的传播是周期性的侧耦合到微腔。该结构在色散关系中同时具有布拉格带隙和(类极化激元)谐振腔带隙。讨论了这两类能隙的成因和物理意义。从有效场形式推导出的耦合模方程在布拉格间隙和谐振腔间隙深处是有效的。

英文摘要:

We use a phenomenological Hamiltonian approach to derive a set of coupled mode equations that describe light propagation in waveguides that are periodically side-coupled to microcavities. The structure exhibits both Bragg gap and (polariton like) resonator gap in the dispersion relation. The origin and physical significance of the two types of gaps are discussed. The coupled-mode equations derived from the effective field formalism are valid deep within the Bragg gaps and resonator gaps.
