| contents | A special class of anisotropic media, hyperbolic metamaterials and metasurfaces (HMMs), has attracted much attention in recent years due to its unique abilities to manipulate and engineer electromagnetic waves on the subwavelength scale. Because all HMM designs require metal dielectric composites, the unavoidable metal loss at optical frequencies inspired the development of active HMMs, where gain materials is incorporated to compensate the metal loss. Here, we experimentally demonstrate an active type II HMM that operates at vacuum wavelength near 750 nm on a silicon platform. Different from previous active HMMs operating below 1 μm, the dielectric constituent in our HMM is solely composed of gain medium, by utilizing solution processed and widely tunable metal halide perovskite gain. Thanks to the facile fabrication, tunability and silicon compatibility of our active HMM, this work paves the way towards HMM's integration into on chip components, and eventually, into photonic integrated circuits. |
