标题： Switching management in couplers with biharmonic longitudinal modulation of refractive index

摘要： 我们研究在相邻通道中具有纵向双调制折射率的耦合器中的光传播。 虽然最简单的单频反相调制允许对严格定义的一组共振频率进行耦合抑制，但多频调制的添加显著改变了共振结构。 因此，双频调制可能抑制主要共振，而三频调制会导致主要共振和次级共振的融合。 显示英文摘要

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.
