光学行为类似于电磁感应透明和吸收的实验中观察到使用耦合熔融二氧化硅微球。这种行为是由两个球体的共共振回音壁模式之间的干涉引起的。观察到耦合谐振腔诱导的透明和吸收。所看到的效果取决于入射光从锥形光纤耦合到第一球体中的强度以及两个球体之间的耦合强度。所观察到的效果可以提高微谐振器在各种应用中的性能。
Optical behavior analogous to electromagnetically induced transparency and absorption is observed in experiments using coupled fused-silica microspheres. This behavior results from interference between coresonant whispering-gallery modes of the two spheres. Coupled-resonator-induced transparency and absorption are observed. Which effect is seen depends on the strength of coupling of incident light from a tapered fiber into the first sphere and on the strength of coupling between the two spheres. The observed effects can enhance microresonator performance in various applications.
