LFA-1/ICAM-1 ligation in human T cells promotes Th1 polarization through a GSK3β signaling–dependent notch pathway
In this study, we report that the integrin LFA-1 cross-linking with its ligand ICAM-1 in human PBMCs or CD4+ T cells promotes Th1 polarization by upregulating IFN-γ secretion and T-bet expression. LFA-1 stimulation in ...
Coherent control of birefringence and optical activity
We show that polarization effects due to anisotropy and chirality affecting a wave propagating through a thin slab of material can be controlled by another electromagnetic wave. No nonlinearity of the metamaterial slab is ...
Coherent control of Snell’s law
We demonstrate coherent control of the generalized Snell’s law in ultrathin gradient metasurfaces constructed by an array of V-shaped slot nanoantennas.
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 ...
