| Popis: |
One major hurdle in the progress of hyperbolic metamaterials (HMMs) is their lossy nature due to the metal constituent. In this work, we design a gain-assisted active HMM utilizing the recently emerged, solution-processed perovskite gain material. Our HMM is consisted of MAPbI3 perovskite and Au subwavelength multi-layer. We theoretically and experimentally investigate the strong emission polarization anisotropy that is unique to HMMs. Our work opens the way towards applications such as high-speed light emission, super resolution imaging and lithography, electro-optical modulators and perfect light absorbers. |
