摘要

我们最近表明,均匀双折射介质表现出一种圆形布拉格现象,这种现象完全依赖于介质参数的共振调谐,而不是特定波长的共振,从而使其电磁响应任意宽带。然而,共振条件需要一个等于平均折射率的手性参数。在这里,我们证明了非轴向波在轴向双各向异性单轴介质中的传播也会产生这样的响应,并且放宽了调谐条件的严重性,为控制共振的位置和相应的带宽提供了方便的平台。此外,还发现了奇点处的异常波传播,在奇点附近可以实现非常高的固有宽带折射率。最近对具有巨大可控制手性的元介质的研究为实现高效光调制器铺平了道路。

Wavelength-Independent Bragg-like Reflection in Uniaxial Bi-Anisotropic Media
We have recently shown that a uniform birefringent medium exhibits a circular Bragg phenomenon that relies solely on resonant tuning of the medium’s parameters, rather than on a particular wavelength resonance, thus rendering its electromagnetic response arbitrarily broadband. The resonant condition, however, necessitated a chirality parameter equal to the average refractive index. Here, we demonstrate that non-axial wave propagation in an axially bi-anisotropic uniaxial medium also enacts such a response and, moreover, relaxes the severity of the tuning condition, offering a convenient platform for controlling both the location of the resonance and the corresponding bandwidth. Anomalous wave propagation at a singular point is additionally identified, in the vicinity of which a remarkably high and intrinsically broadband refractive index can be realized. Recent demonstrations of meta-media with giant and controllable chirality pave the path towards the realistic embodiment of a highly efficient optical modulator.
