It is shown here how encapsulated graphene devices can be laterally coupled to plasmonic metasurfaces via 1D edge contacts, preserving the high mobility of encapsulated graphene while enhancing optical coupling. The device is used for photodetection

Metamaterial resonances have demonstrated outstanding abilities to control electromagnetic waves, which brings promises to directly use them to create unique channels for electromagnetic wave tunneling through barriers. Herein, an electromagnetic wav

Planar diffractive lenses, with metamaterial artificial structures and subwavelength thickness, provide unique and flexible platforms for optical design in the terahertz (THz) regime. Here, we present a metamaterial-based Rayleigh-Wood Fresnel-zone-p

We demonstrate a miniaturized, high sensitivity magnetometer by combining micrometer vapor cells and polarization selective dielectric metasurfaces. With Bell-Bloom scheme[1] we obtained magnetic field sensitivity of ~ 3 p T / H z , paving the way to

Achieving high-Q resonances in the THz frequency range is significant for applications such as sensors, filters, and emitters. A promising approach for obtaining such resonances is by using metamaterials. However, high-Q resonances in THz metamateria

Electromagnetic wave experiences phase changing both in propagation and resonance. Extreme phase changing is interesting and has its applications. Here we report a phase singularity phenomenon in double-layer metamaterial.
