论文摘要
中尺度介电球的宽带光照明使揭示与超级共振模式相关的新效果成为可能。其中包括产生高阶Fano共振级联反应的可能性。质量因子的顺序Q = 10^7。在宽带光照射下通过中尺度电介质球定位了超高共振的亚径流场(例如,在波带400-700 nm的波带处于球体的折射率n = 1.5-1.9和1500-1600 nm n = 3.47中)。建立了超响应峰的准周期性条件。显示了Fano级联反应在球体折射率上的振幅调制的依赖性。这些结果在对与超基质模式相关的超分辨率机制的物理学的深入了解中很重要,并且会在许多其他领域找到巨大的潜在应用。
Broadband light illumination of a mesoscale dielectric sphere makes it possible to reveal new effects that associated with super resonance mode. These include the possibility of generating high-order Fano resonance cascades. The quality factor has the order Q=10^7. Super-resonance-enabled subdiffraction fields localization by mesoscale dielectric sphere under broadband light illuminations (e.g., at wavebands of 400 - 700 nm for refractive index of sphere n=1.5-1.9 and 1500 - 1600 nm for n=3.47) have been investigated. The conditions for the quasi-periodicity of superresonance peaks are established. The dependence of the amplitude modulation of Fano cascades on the refractive index of the sphere is shown. These results are important in deep understanding of physics of the super-resolution mechanism related to superresonance mode and will find great potential applications in many other area.
