具有refractive index的双谐波纵向调制的耦合器中的切换管理
Switching management in couplers with biharmonic longitudinal modulation of refractive index
摘要：
我们解决了光在耦合器中的传播与纵向双谐波调制的折射率在相邻的通道。虽然最简单的单频异相调制允许抑制严格定义的一组谐振频率的耦合，但是在多个频率上添加调制显著地修改了谐振的结构。因此，对倍频的附加调制可以抑制主共振，而对三频的调制导致主共振和次共振的融合。
英文摘要：
We address light propagation in couplers with longitudinal biharmonic modulation of refractive index in neighboring channels. While simplest single-frequency out-of-phase modulation allows suppression of coupling for strictly defined set of resonant frequencies, the addition of modulation on multiple frequency dramatically modifies the structure of resonances. Thus, additional modulation on double frequency may suppress primary resonance, while modulation on triple frequency causes fusion of primary and secondary resonances.
