All-optical active THz metasurfaces for ultrafast polarization switching and dynamic beam splitting
Miniaturized ultrafast switchable optical components with an extremely compact size and a high-speed response will be the core of next-generation all-optical devices instead of traditional integrated circuits, which are ...
Tunable electromagnetically induced transparency in coupled three-dimensional split-ring-resonator metamaterials
Metamaterials have recently enabled coupling induced transparency due to interference effects in coupled subwavelength resonators. In this work, we present a three dimensional (3-D) metamaterial design with six-fold ...
Giant enhancement in Goos-Hänchen shift at the singular phase of a nanophotonic cavity
In this letter, we experimentally demonstrate thirtyfold enhancement in Goos-Hänchen shift at the Brewster angle of a nanophotonic cavity that operates at the wavelength of 632.8 nm. In particular, the point-of-darkness ...
