破超对称动态无反射光放大器
Broken-SUSY dynamic reflectionless optical amplifier
摘要：
破缺超对称性被用来定义一个无反射的有源腔，能够放大可见光中的电磁辐射。该方法是分析通过使用达布变换的产生的光学势和计算其解决方案，而传输/反射光谱的评估是用传递矩阵法。有趣的是，所提出的装置表现为放大以大角度到达的辐射的动态光学滤波器，而对于其他方向几乎完全透明。因此，简单地通过旋转可以获得不同的功能。此外，有源滤波器对于所有波长和入射角都是无反射的。必要的Kramers-Kronig关系也满足与Drude模型在高频下兼容的模型，即远离吸收共振。
英文摘要：
Broken-supersymmetry is used to define a reflectionless active cavity capable of amplifying electromagnetic radiation in the visible. The approach is analytical through the use of the Darboux transform for the generation of the optical potential and the calculation of its solution, while the transmission/reflection spectra evaluation is done with the Transfer Matrix method. Interestingly, the proposed device behaves as a dynamic optical filter amplifying radiation arriving at large angles while for other directions is almost completely transparent. Thus, simply by rotation different functionalities can be obtained. In addition the active filter is reflectionless for all wavelengths and angles of incidence. The necessary Kramers-Kronig relations are also satisfied being the model compatible with the Drude model at high frequency i.e. far from absorption resonances.
