超对称性激发的一维变换光学

SUSY-inspired one-dimensional transformation optics

Mohammad-Ali Miri, Matthias Heinrich, Demetrios N. Christodoulides

摘要:

变换光学旨在通过相关的坐标变换来识别具有所需电磁特性的人造材料和结构。一般来说,这样的方案是为了适当地调整超材料的本构参数,以便控制光在二维和三维中的轨迹。在这里,我们介绍了一类新的一维光学变换,利用超对称性(SUSY)的数学框架。这种系统的方法可以用来合成光子配置具有相同的反射和透射特性,下降到相位,对于所有的入射角,从而使它们完全无法区分外部观察者。沿着这些思路,低对比度电介质排列可以设计成完全模仿给定高对比度结构的行为,否则可用材料和现有制造技术将无法达到这些行为。也可以采用类似的策略来替换负介电常数域,从而避免不必要的光损耗。

英文摘要:

Transformation optics aims to identify artificial materials and structures with desired electromagnetic properties by means of pertinent coordinate transformations. In general, such schemes are meant to appropriately tailor the constitutive parameters of metamaterials in order to control the trajectory of light in two and three dimensions. Here we introduce a new class of one-dimensional optical transformations that exploits the mathematical framework of supersymmetry (SUSY). This systematic approach can be utilized to synthesize photonic configurations with identical reflection and transmission characteristics, down to the phase, for all incident angles, thus rendering them perfectly indistinguishable to an external observer. Along these lines, low-contrast dielectric arrangements can be designed to fully mimic the behavior of a given high-contrast structure that would have been otherwise beyond the reach of available materials and existing fabrication techniques. Similar strategies can also be adopted to replace negative-permittivity domains, thus averting unwanted optical losses.
