In this Letter, a fundamentally new concept of realization of hyperbolic plasmonic metasurfaces by anisotropic gain-loss competition is proposed, and the possibility of highly directional propagation and amplification of surface plasmon polaritons is predicted. A simple realistic configuration of such a metasurface represents the periodic array of lossy metallic slabs embedded in the gain matrix. Our results may pave the way for numerous applications ranging from integrated and highly directional quantum light emitters to nonlinear-optical frequency converters.
在本信函中，提出了一种通过各向异性增益-损耗竞争实现双曲线等离子体超表面的全新概念，并预测了表面等离激元极化激元的高定向传播和放大的可能性。这种超表面的一种简单且实际的结构是嵌入增益矩阵中的有损金属平板的周期性阵列。我们的结果可能为从集成且高定向量子光发射器到非线性光学频率转换器等众多应用铺平道路。
